Synthesis, structure and magnetic properties of a novel 1D coordination polymer {[Cu2(amtrz)4(1,1-μ-NCS)2](ClO4)2 · H2O}n

A novel one-dimensional (1D) coordination polymer {[Cu2(amtrz)4(1,1-μ-NCS)2](ClO4)2 · 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 S⋯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 = −51.3 cm−1.
