A 2D CuII complex containing ferromagnetically coupled 1D chain with threefold bridging ligands

A new 2D CuII complex [Cu(μ1,1-N3)(tp)(CH3OH)]n (tp = terephthalate) (1) has been synthesized and characterized structurally and magnetically. Single-crystal structural analysis shows that complex 1 consists of 1D CuII chains containing threefold bridging ligands, one μ-1,1-azido, one (syn–syn) terephthalate and one methanol, which are bridged via terephthalate anions to afford a 2D network. Magnetic measurements indicate that complex 1 exhibits intrachain ferromagnetic interaction with J = 63(2) cm−1.
