Abstract Reactions 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 [Pt2(d(py)pe)2Ag4(NO3)8(H2O)2]n(1 ) and [Pt2(d(py)pcp)2Ag6(NO3)10] n (2), respectively, which contain Pt2L 2 4+ cores with each L ligand nowP,N-bridging two Pt-atoms; these Pt2 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 ∼2.76 Å indicative of bonding.
