Catena-poly [[bis [tris (4-meth­­oxy­phen­yl) phosphine-κP] silver (I)] -μ-thio­cyanato-κ2N:S]

Abstract

The coordination polymer, [Ag(NCS)(C21H21O3P)2]n or {[Ag(P(4-OMePh)3)2]-μ-NCS}n, features μ-thio­cyanato ligands bridging between neighbouring silver(I) atoms, generating chains along the b-axis direction. Each AgI atom is four-coordinate, with two phospho­rus donors from two distinct tris­(p-meth­oxy­phen­yl)phosphine ligands, and two atoms from the thio­cyanato ligands in severely distorted tetra­hedral shape. The Ag—P [2.4331 (6) and 2.4625 (5) Å], Ag—N [2.339 (2) Å] and Ag—S [2.6760 (6) Å] bond lengths all appear within the expected ranges, with corresponding P—Ag—P and S—Ag—N angles of 129.610 (19) and 86.75 (6)°. In the crystal, the polymeric chains pack into layers parallel to (001) separated by the aryl groups of the phosphine ligands.
