ABSTRACT
The title compound, [CuCl2(C8H14N8O)], is the first structurally characterized molecular chelate complex of a binuclear N-substituted tetrazole. The Cu atom is five-coordinate, with an approximately square-pyramidal geometry. The equatorial positions of the pyramid are occupied by two Cl atoms and two N atoms from the ligand molecule; the O atom of the ligand lies in the axial position. Each complex is connected to four others via weak C-H...Cl and C-H...N interactions, forming sheets parallel to the (010) plane.
ABSTRACT
In the title compound, C8H6N4O2, the tetrazole and benzene rings are planar to within 0.001 (1) and 0.007 (1) A, respectively. These rings are not coplanar in the molecule, the dihedral angle between them being 52.90 (4) degrees. Molecules are connected together by O-H...N and C-H...O hydrogen bonds, forming two-dimensional networks parallel to the xz plane with van der Waals interactions between them.
ABSTRACT
There are two symmetry-independent molecules in the unit cell of the title compound, C(7)H(5)N(5)O(3). The tetrazole and phenyl rings are essentially planar and are not coplanar in either molecule [dihedral angles 30.2 (1) and 7.0 (1) degrees]. In the structure, four molecules are connected by O-H...N bridges, forming four-membered molecular aggregates which are linked together by a complex three-dimensional hydrogen-bond network.
