title: catena-Poly[[[triaqua-sulfatozinc(II)]-μ-3,3'-bis-(3-pyrid-yl)-1,1'-(m-phenyl-ene)diurea] methanol solvate monohydrate].
abstract: In the title coordination polymer, {[Zn(SO(4))(C(18)H(16)N(6)O(2))(H(2)O)(3)]·CH(3)OH·H(2)O}(n), the Zn(2+) ion adopts a slightly distorted cis-ZnN(2)O(4) octa-hedral geometry arising from three coordinated water mol-ecules, one sulfate ion and two bridging 3,3'-bis-(3-pyrid-yl)-1,1'-(m-phenyl-ene)diurea (bpmpbu) ligands. The dihedral angles between the central benzene ring and two terminal pyridine rings of the bpmbpu mol-ecule are 10.58 (17) and 34.63 (16)°. In the crystal, the ligands bridge the Zn(II) ions, thus generating a one-dimensional zigzag coordination polymer propagating in [010]. The crystal structure features extensive N-H⋯O and O-H⋯O hydrogen-bonding inter-actions.
