[(E)-But-2-enoato-κO]chlorido(2,2′-diamino-4,4′-bi-1,3-thia­zole-κ(2) N (3),N (3′))zinc(II) monohydrate

In the title compound, [Zn(C(4)H(5)O(2))Cl(C(6)H(6)N(4)S(2))]·H(2)O, the Zn(II) cation is coordinated by a bidentate diamino­bithia­zole (DABT) ligand, a but-2-enoate anion and a Cl(−) anion in a distorted tetra­hedral geometry. Within the DABT ligand, the two thia­zole rings are twisted to each other at a dihedral angle of 4.38 (10)°. An intra­molecular N—H⋯O inter­action occurs. The centroid–centroid distance of 3.6650 (17) Å and partially overlapped arrangement between nearly parallel thia­zole rings of adjacent complexes indicate the existence of π–π stacking in the crystal structure. Extensive O—H⋯Cl, O—H⋯O, N—H⋯Cl and N—H⋯O hydrogen bonding helps to stabilize the crystal structure.
