Seven copper (I) complexes of diphosphine ligands and N^N ligands: Syntheses, structural characterizations and spectroscopic properties

The reactions of diphosphine ligands and nitrogen-containing ligands with Cu(I) salts in the mixed solvents of methanol (MeOH) and dichloromethane (CH2Cl2) generated the corresponding complexes, {[Cu(dppbe)(Bphen)](ClO4)¡¤2CH3OH}n (1), {[Cu2(dppe)(dmp)2(CN)2]¡¤2CH3OH}n (2), {[Cu2(dppb)(dmp)2I2]¡¤2CH3OH}n (3), [Cu(POP)(C16H6N6)]I (4), {[Cu(POP)(C16H6N6)](SCN)}n (5), [Cu(xantphos)(bpy)](ClO4) (6) and {[Cu(xantphos)(bpy)](CF3SO3)}n (7) {dppbe = 1,2-bis(diphenylphosphanyl)benzene, dppe = 1,2-bis(diphenylphosphino)ethane; dppb = 1,4-bis(diphenylphosphino)butane, POP = bis[2-(diphenylphosphino)phenyl]ether, xantphos = 4,5-bis (diphenylphosphio)-9,9-dimethylxanthene, Bphen = 4,7-diphenyl-1,10-phenanthroline, dmp = 2,9-dimethyl-1,10-phenanthroline, C16H6N6 = [2,3-f]-pyrazino-[1,10]phenanthroline-2,3-dicarbonitrile, bpy = 2,2?-bipyridine}. These complexes were all characterized by single-crystal X-ray crystallography, elemental analysis, IR, 1H NMR spectroscopy, luminescence and THz spectroscopy. Complexes 1 and 2 consist of 1D infinite zigzag chain structures which are linked by hydrogen bonds, while complexes 3, 5 and 7 have 2D topological architectures which are connected by hydrogen bonds, complex 4 has an annular structure and complex 6 is a mononuclear structure. The types of hydrogen bonds, choice of solvents and coordination modes of the ligands are of importance in defining the structural and topological features of the resulting networks. Furthermore, complexes 1?7 exhibit interesting luminescence in the solid state at room temperature. Complexes 1?3 can act as yellow luminophores, complex 4 acts as a red luminophore, complex 5 acts as an orange luminophore and complexes 6?7 act as green luminophores. Their terahertz spectra show more accurate characteristics of their structures.

Synthesis and characterization of bridged and chelated diphosphine coordinated transition metal chalcogenide clusters,

Ferrocenyl diphosphine containing iron-palladium clusters [(CO) 6Fe2(mu3-Y)2Pd{PPh 2(eta5-C5H4)Fe(eta5- C5H4)PPh2})] (Y = Se (9); Y = Te (10)) have been prepared by the room temperature reaction of [(CO)6Fe 2(mu3-Y)2Pd(PPh3)2] (Y = Se(5), Te(6)) with dppf. Structural characterization reveals an unusual chelating coordination by ferrocenyl diphosphine ligand attached to palladium atom. Room temperature reactions of dppe with metal clusters [Fe 3(mu3-Te)2(CO)9] (1), [Fe 3(mu3-Te)2(CO)8PPh3] (2) and [(CO)6Fe2(mu3-Y) 2Pd(PPh3)2] (Y = Se(5), Te(6)) have been performed to obtain chalcogenide metal clusters [(CO)18Fe 6(mu3-Te)4{mu-PPh2(CH 2)2PPh2}] (3), [Fe3(mu 3-Te)2(CO)8{PPh2(CH 2)2PPh2}] (4) and [(CO)6Fe 2(mu3-Y)2Pd{PPh2(CH 2)2PPh2}] (Y = Se (7); Y = Te (8)) respectively. In all the compounds the diphosphine ligands are attached to metal centres by forming either chelating or bridging mode. The structures of compounds 3, 4, 7 and 9 have been established by single crystal X-ray crystallography.

Oligophosphine-thiocyanate Copper(I) and Silver(I) Complexes and Their Borane Derivatives Showing Delayed Fluorescence

The series of chelating phosphine ligands, which contain bidentate P2 (bis[(2-diphenylphosphino)phenyl] ether, DPEphos; 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene, Xantphos; 1,2-bis(diphenylphosphino)benzene, dppb), tridentate P3 (bis(2-diphenylphosphinophenyl)phenylphosphine), and tetradentate P4 (tris(2-diphenylphosphino)phenylphosphine) ligands, was used for the preparation of the corresponding dinuclear [M(mu2-SCN)P2]2 (M = Cu, 1, 3, 5; M = Ag, 2, 4, 6) and mononuclear [CuNCS(P3/P4)] (7, 9) and [AgSCN(P3/P4)] (8, 10) complexes. The reactions of P4 with silver salts in a 1:2 molar ratio produce tetranuclear clusters [Ag2(mu3-SCN)(t-SCN)(P4)]2 (11) and [Ag2(mu3-SCN)(P4)]22+ (12). Complexes 7-11 bearing terminally coordinated SCN ligands were efficiently converted into derivatives 13-17 with the weakly coordinating -SCN:B(C6F5)3 isothiocyanatoborate ligand. Compounds 1 and 5-17 exhibit thermally activated delayed fluorescence (TADF) behavior in the solid state. The excited states of thiocyanate species are dominated by the ligand to ligand SCN ? pi(phosphine) charge transfer transitions mixed with a variable contribution of MLCT. The boronation of SCN groups changes the nature of both the S1 and T1 states to (L + M)LCT d,p(M, P) ? pi(phosphine). The localization of the excited states on the aromatic systems of the phosphine ligands determines a wide range of luminescence energies achieved for the title complexes (lambdaem varies from 448 nm for 1 to 630 nm for 10c). The emission of compounds 10 and 15, based on the P4 ligand, strongly depends on the solid-state packing (lambdaem = 505 and 625 nm for two crystalline forms of 15), which affects structural reorganizations accompanying the formation of electronically excited states.
