The unsymmetrical phosphorus ylide, Ph 2 PCH 2 CH 2 PPh 2 C(H)C(O)Ph is shown to react with Hg(II) halides to form polymeric products with the composition {HgX 2 [PPh 2 CH 2 CH 2 PPh 2 C(H)C(O)Ph]} n , where X=Cl (1), Br (2), I (3). The complexes have been characterized by elemental analysis, IR, 1 H, 31 ...
The reaction of mercury(II) halides with 1,2-bis(diphenylphosphino)ethane monoxide (dppeO) in 1:1 molar ratio yielded P,O-coordinated polymers having the empirical formula [HgX 2 (dppeO)] n [X=Cl (1), Br (2), I (3)]. In contrast, the reaction between the same reactants in a 1:2 molar ratio yielded the P, P-coordinated monomeric complexes, HgX 2 (dppeO) 2 [X=Cl (4),...
