Synthesis, structure and magnetic properties of a novel 1D coordination polymer {[Cu-2(amtrz)(4)(1,1-mu-NCS)(2)](ClO4)(2)center dot H2O}(n)

A novel one-dimensional (1D) coordination polymer {[Cu-2(amtrz)(4)(1,1-mu-NCS)(2)](ClO4)(2)center dot H2O}(n) (1) (amtrz = 4-amino-1,2,4-triazole) was synthesized and structurally characterized. The 1D chains of 1 are linked via short intermolecular (SS)-S-... interactions to form a 3D supramolecular architecture with 1D channels along c direction, while water molecules and perchlorate anions were encapsulated in the channels. Variable-temperature magnetic susceptibilities (2-300 K) shows antiferromagnetic interactions with J = -51 cm(-1). (c) 2006 Elsevier B.V. All rights reserved.
