Abstract

Hydrothermal reactions of copper(II) and cobalt(II) salts with 1-tetrazole-phenyl-4-methylphosphonic acid yielded the coordination polymers [Cu(H2O)(HO3PCH2C6H4CN4)]·H2O (1·H2O) and [Co(H2O)2(HO3PCH2C6H4CN4H)2]·2H2O (2·2H2O). Compound 1·H2O is two dimensional and is constructed from chains of trans-corner sharing, ‘4+2’ axially distorted {CuO4N2} octahedra. These chains are linked through the organic tethers of the ligands in the doubly deprotonated form{HO3PCH2C6H4CN4}2− to propagate in two-dimensions. In contrast, compound 2·2H2O is one-dimensional and features {CoO4N2} octahedra linked through pairs of ligands in the singly deprotonated form {HO3PCH2C6H4CN4H}−1, i.e. with the tetrazole terminus in the neutral form. The magnetic properties of compound 1·H2O reflect the structure where the Cu(II) ions are bridged by syn-syn phosphate and tetrazolate Cu-N-N-Cu bridges, with the former linkage likely to transfer ferromagnetic coupling whereas the latter leads to antiferromagnetic coupling. The two competing pathways lead to negligible overall coupling.
