Two polymorphs of dinuclear mercury-iron complexes, [HgBr2(dppf)] (1) where dppf is 1,1′-bis (diphenylphosphino)ferrocene, are prepared and crystal structures are determined by X-ray crystallography. The reaction of mercury(II) bromide with dppf in methanol-dichloromethane led to orange block polymorph. After crystallization of this complex in DMSO, a red needle polymorph was obtained.

Reaction of Cp4Fe4(CO)4 (1) with RLi and HBF4 in sequence affords Cp3Fe4(CO)4(C5H4R) (R= Me, Bun, and Ph) in moderate yields. Further sequential PhLi/HBF4 treatment of Cp3Fe4(CO)4(C5H4Ph) produces Cp2Fe4(CO)4(C5H4Ph) 2. On the other hand, 1 reacts with lithium diisopropylamide (LDA) and bromoferrocene sequentially to produce a ferrocenylated cluster [Cp3Fe4(CO)4(C5H 4)][(C5H4)FeCp] (3) and a double cluster [Cp3Fe4(CO)4(C5H4)] 2 (2). A similar LDA/dibromoferrocene treatment with 1 leads to 2, [Cp3Fe4(CO)4(C5H 4)][(C5H4)(C5H4Br)Fe] (4), and a ferrocenyl-bridged double cluster [Cp3Fe4(CO)4(C5H4)] 2[(C5H4)2Fe] (5). The new compounds have been characterized by elemental analysis and IR, mass, and NMR spectroscopy.

Reaction of polymeric gold(I) acetylide species (bpyC?CAu) n (bpyC?CH = 5-ethynyl-2,2?-bipyridine) with diphosphine ligands Ph2P(CH2)nPPh2 (n = 2-6) or 1,1?-bis(diphenylphosphino)-ferrocene (dppf) in dichloromethane induces isolation of binuclear gold(I) complexes (bpyC?CAu)2{mu- Ph2P(CH2)nPPh2} or (bpyC?CAu)2(mu-dppf). Complexation of Ln(hfac)3 (hfac = hexafluoroacetylacetonate, Ln = Nd, Eu, Er, Yb) subunits to the binuclear gold(I) complexes through 2,2?-bipyridyl chelation gives the corresponding Au4Ln4 or Au2Ln2 heteropolynuclear complexes. Noticeably, upon formation of the Au 4Ln4 arrays by complexation of (bpyC?CAu) 2(mu-Ph2P(CH2)4PPh2) (3) with Ln(hfac)3 units, trans-conformation in 3 transforms dramatically to the cis-arranged form due to the strong driving force from ligand-unsupported Au-Au contacts between two Au2Ln2 subunits. In contrast, cis-conformation in (bpyC?CAu)2(mu- dppf) (6) stabilized by Au-Au interactions is reversed to the trans-oriented form upon formation of Au2Ln2 arrays by introducing Ln(hfac)3 units through 2,2-bipyridyl chelation. The binuclear gold(I) complexes show bright blue luminescence featured by ligand-centered pi ? pi* (C?Cbpy) states together with low-energy emission at 500-540 nm, associated with 3(pi?pi*) excited states, mixed probably with some characteristic from (Au-Au) ? (C?Cbpy) 3MMLCT transition. For Au4Ln4 or Au 2Ln2 complexes, sensitized lanthanide luminescence is achieved by energy transfer from Au-acetylide chromophores with lifetimes in the sub-millisecond range for EuIII complexes, whereas in the microsecond range for near-infrared emitting NdIII, ErIII, and YbIII species.

A series of air-stable nickel complexes of the form L2Ni(aryl) X (L = monodentate phosphine, X = Cl, Br) and LNi(aryl)X (L = bis-phosphine) have been synthesized and are presented as a library of precatalysts suitable for a wide variety of nickel-catalyzed transformations. These complexes are easily synthesized from low-cost NiCl2·6H2O or NiBr 2·3H2O and the desired ligand followed by addition of 1 equiv of Grignard reagent. A selection of these complexes were characterized by single-crystal X-ray diffraction, and an analysis of their structural features is provided. A case study of their use as precatalysts for the nickel-catalyzed carbonyl-ene reaction is presented, showing superior reactivity in comparison to reactions using Ni(cod)2. Furthermore, as the precatalysts are all stable to air, no glovebox or inert-atmosphere techniques are required to make use of these complexes for nickel-catalyzed reactions.

Re(V)-imido and Re(V)-oxo complexes containing 1,1?-bis(diphenylphosphino)ferrocene (Fe(eta5-C5H4PPh2)2, dppf) were prepared from mer,trans-Re(O)Cl3(PPh3)2 (1), mer,trans-Re(NPh)Cl3(PPh3)2 (2), or mer,cis-Re(N-C6H3-2,6-i-Pr2)2Cl 3(py) (3). Compounds 1-3 reacted with dppf to give fac-Re(O)Cl3(dppf) (4), fac-Re(NPh)Cl3(dppf) (5), and mer-Re(N-C6H3-2,6-i-Pr2)Cl3(dppf) (6), respectively. Electrochemical studies performed on Re-oxo-dppf complexes (4) and Re-imido-dppf complexes (5 and 6) showed different redox behavior depending on the type of ligand coordinated to the Re metal. The structure of compound 4 was determined by X-ray diffraction.

Diphosphine-bridged dimers of oxo-centered triruthenium-acetate cluster units, i.e., [{Ru3O(OAc)6(py)2} 2(dppan)](PF6)2 (2) and [{Ru 3O(OAc)6(py)2}2(dppf)](PF 6)2 (3) were prepared by reaction of 2.3 equivalent [Ru3O(OAc)6(py)2(CH3OH)](PF 6) with 9,10-bis(diphenylphosphino)anthracene (dppan) or 1,1?-bis(diphenylphosphino)ferrocene (dppf), respectively. Apparent redox wave splitting is observed in complex 2, revealing the presence of electronic communication between two triruthenium units mediated through bridging dppan. The complexes were characterized by elemental analysis, IR, UV-Vis, 31P NMR, and ES-MS spectroscopies, and cyclic and differential-pulse voltammetry. The crystal structure of complex 3 was determined by X-ray crystallography.

New silver(I) complexes have been synthesised from the reaction of AgNO3, monodentate PR3 (PR3 = P(o-tolyl)3, P(m-tolyl)3, P(p-tolyl)3, P(p-C6H4F), SeP(C6H5)3) or bidentate tertiary (dppe = bis(diphenylphosphane)ethane, dppf = 1,1?-bis(diphenylphosphane)ferrocene) phosphanes and potassium dihydrobis(3-nitro-1,2,4-triazolyl)borate, K[H2B(tzNO2)2]. These compounds have been characterized by elemental analyses, FT-IR, ESI-MS and multinuclear (1H and 31P) NMR spectral data. The adduct {[H2B(tzNO2)2]Ag[P(m-tolyl)3]2} has been characterized by single crystal X-ray studies. In the former, the H2B(tzNO2)2 acts as a monodentate ligand utilizing the coordinating capability of only one of the additional (exo-) ring nitrogens to complete the coordination array about the silver atom.
