catena-Poly[silver(I)-bis[μ-bis(diphenylphosphino)methane-κ2P:P′]-μ-thiocyanato-κ2S:S-silver(I)-μ-thiocyanato-κ2S:N]

Abstract

The title compound, [Ag(NCS)(C25H22P2)]n, contains two Ag+ ions, two thiocyanate ions and two bis(diphenylphosphino)methane (dppm) ligands in the asymmetric unit. One of the thiocyanate ions bridges the two Ag+ ions in a μ2-mode from its S atom and the two dppm ligands bridge the silver ions in a μ1,μ1 mode. The remaining SCN− ion bridges the binuclear units via its N and S atoms, generating a one-dimensional polymer propagating in [overline{1}01]: the resulting AgP2SN and AgP2S2 coordination geometries could be described as distorted tetrahedral.
