title: catena-Poly[[[[2-(2-pyridyl-κN)-1H-benzimidazole-κN]copper(II)]-μ-l-methio-ninato-κN,O:O'] perchlorate].
abstract: The structure of the title compound, {[Cu(C(5)H(10)NO(2)S)(C(12)H(9)N(3))]ClO(4)}(n), has ortho-rhom-bic symmetry. The chain structure is constructed from square-pyramidally coordinated Cu(II) atoms linked through l-methio-nate ligands. The chains propagate along the a-axis direction and are linked to perchlorate anions via N-H⋯O hydrogen bonds.
