Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 19845-69-3, C30H32P2. A document type is Article, introducing its new discovery.
The reaction of digold(I) diphosphine complexes [Au2(O2CCF3)2(mu-Ph2P-X -PPh2)] with dithiols HS-Y-SH can give either macrocyclic complexes [Au2(mu-S-Y-S)(mu-Ph2P-X-PPh2)] or polymeric complexes [Au2(mu-S-Y-S)(mu-Ph2P-X-PPh2)] n. The structures of the macrocyclic complex [Au2{mu-(S-4-C6H4)2S}{mu -Ph2P(CH2)4PPh2}], and the polymeric complexes [Aun{mu-(S-CH2CO2CH2CH 2O)2-1,4-C6H4}n(mu- trans-Ph2PCH{double bond, long}CHPPh2)n] and [Aun{mu-(S-CH2CO2CH2CH 2O)2-1,5-C10H6}n(mu -trans-Ph2PCH{double bond, long}CHPPh2)n] have been determined. Evidence is presented that the complexes exist primarily as macrocycles in solution and that, in favorable cases, ring-opening polymerization occurs during crystallization.
