A coordination polymer consisting of two different one-dimensional copper(II) chains

Y. Wu, W.-Z. Wang, R. H. Ismayilov, G.-H. Lee and S.-M. Peng

Synopsis: CuII atoms exhibit different octa­hedral coordination geometries in two crystallographically independent one-dimensional chains. Extensive hydrogen bonding is observed among perchlorate anions, water mol­ecules and N-(4-methyl­pyrimidin-2-yl)pyrazin-2-amine ligands, and the one-dimensional chains are further linked to form a three-dimensional structure through inter­chain O-H...O and N-H...O hydrogen-bonding inter­actions.

Formula: A [Cu(C9H9N5)(CH4O)(H2O)2] complex
