The title three-dimensional coordination polymer, [Cu(2)Cl(C(6)H(4)N(5))](n), is the product of the hydro-thermal reaction of CuCl(2)·2H(2)O and 5-(4-pyrid-yl)-1H-tetra-zole (4-Hptz). The two independent Cu(I) ions are coordinated in distorted tetra-hedral and distorted trigonal coordination environments. In the unique 5-(4-pyrid-yl)-1H-tetra-zolate ligand, the dihedral angle between the pyridi...

In the title mol-ecule, C(9)H(10)BrN(3)O(2)S, the thia-zine ring has an envelope conformation with the S atom at the flap. The geometry around the S atom is distorted tetra-hedral. In the crystal, inversion dimers linked by pairs of N-H⋯N hydrogen bonds occur, generating R(2) (2)(6) ring motifs. N-H⋯O hydrogen bonds and C-H⋯O inter-actions connect the dimers, forming a three-dimentional network...

The title compound, (C(6)H(9)N(2))(2)[CuCl(4)], contains a distorted tetra-hedral [CuCl(4)](2-) anion and two protonated amino-pyridinium cations. The geometries of the protonated amino-pyridinium cations reveal amine-imine tautomerism.
