Novel 3-D PtS-like tetrazolate-bridged manganese(II) complex exhibiting spin-canted antiferromagnetism and field-induced spin-flop transition.

Abstract

Two novel manganese(II) tetrazolate coordination polymers, Mn 3(Hbta) 4(mu 2 -OH) 2(H 2O).2H 2O ( 1) and Mn(bta)(H 2O) ( 2), were obtained by the hydrothermal reaction of MnCl 2.4H 2O with N, N-bis[1(2) H-tetrazol-5-yl]amine (H 2bta) in different pH values. Compound 1 exhibits a 2-D (4,4) layer structure, which is built from binuclear Mn 2(mu 2-OH) 2 subunits and mu 3-bridging Hbta (-) linkers. Compound 2 is a helical framework, and its 3-D PtS-like net is constructed by Mn 2(bta) 2 dimers and mu 5-bridging bta (2-) linkers. Magnetic measurements reveal that compound 1 displays an antiferromagnetic ordering, while compound 2 exhibits the coexistence of a spin-canted antiferromagnetic coupling and a field-induced spin-flop transition.
