Abstract

Reactions of PtI2L (L = P,P-bonded 1,2-bis(2-pyridyl )phosphino)ethane, d(py)pe, or 1,2-bis((2-pyridyl)phosphino)cyclopentane, d(py)pcp) with excess AgNO3 in acetic acid/ethanol afford the polymers [Pt-2(d(py)pe)(2)Ag-4(NO3)(8) (H2O)(2)](n) (1) and [Pt-2(d(py)pcp)(2) Ag-6(NO3)(10)](n) (2), respectively, which contain Pt2L24+ cores with each L ligand now P,N-bridging two Pt-atoms; these Pt-2 cores are connected via bridging AgNO3 clusters, the Ag being bound to the pyridyl-N or nitrate-O atoms. X-ray crystallographic data reveal Pt-Pt contacts of similar to 2.76 Angstrom indicative of bonding.
