Poly[[{μ(3)-tris-[2-(4-phenyl-1,2,3-triazol-1-yl)eth-yl]amine}silver(I)] hexa-fluorido-phosphate]

Abstract

The title compound, {[Ag(L)]PF(6))(n) {L is tris-[2-(4-phenyl-1,2,3-triazol-1-yl)eth-yl]amine, C(30)H(30)N(10)}, consists of alternating two-dimensional cationic layers of [Ag(L)](+) and anionic PF(6) (-) layers. Each Ag(I) atom is three coordinated in a T-shaped geometry by three N atoms from three ligands. Each ligand links three Ag(I) atoms, generating a two-dimensional network structure with two different metallacycles, A and B. In A, eight coordination units from four ligands connect four Ag(I) atoms, forming a 48-membered ring. In B, four coordination units from two ligands link two Ag(I) atoms, forming a 24-membered ring. Each B ring is surrounded by four A rings, and each A ring has four A and four B rings as neighbours. This cationic layer thus generates a 4.8(2) topology network, with each Ag(I) centre and ligand acting as a three-connected topological node.
