A 2-D ladder-type polymer, Mn2(NIT2-thz)2Cl4(H2O)2: synthesis, crystal structure and magnetic properties

A novel Mn(II)-nitronyl nitroxide-substituted thiazole complex Mn2(NIT2-thz)2Cl4(H2O)2 (NIT2-thz=2-(2′-thiazole)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide) was synthesized and characterized structurally and magnetically. It crystallizes in the orthorhombic space group Pbca. The complex has dimeric structure where two manganese ions are doubly bridged by chloride ions. Each manganese ion is in a distorted octahedral environment. The complex molecules were connected as two-dimensional ladder-type structure by the intermolecular interaction. Magnetic measurements show that there are three kinds of antiferromagnetic interactions in the compound.
