Abstract
The title complex, tetraaqua{1-[(1H-benzotriazol-1-yl)methyl]-1H-1,2,4-triazole-κN 4}(sulfato-κO)copper(II) sesquihydrate, [Cu(SO4)(C9H8N6)(H2O)4]·1.5H2O, is composed of one copper atom, one 1-[(2H-benzotriazol-1-yl)methyl]-1-H-1,2,4-triazole (bmt) ligand, one sulfate ligand, four coordinated water molecules and one and a half uncoordinated water molecules. The CuII atom is six-coordinated by one N atom from a bmt ligand and five O atoms from the monodentate sulfate ligand and four water molecules in a distorted octahedral geometry. In the crystal, adjacent molecules are linked through O—H⋯O and O—H⋯N hydrogen bonds involving the sulfate anion and the coordinated and uncoordinated water molecules into a three-dimensional network.

Summary
A new copper(II) complex based on 1-[(1H-benzotriazol-1-yl)methyl]-1H1,2,4-triazole.
