RESUMO
In the title compound, (C9H8N)2[ZnCl4]·2H2O, the tetra-chlorido-zincate ion is located on a twofold rotation axis with the Zn atom on a special position. The crystal packing is stabilized by N-Hâ¯O and O-Hâ¯Cl inter-actions.
RESUMO
The whole mol-ecule of the title compound, [NiCl2(C3H4N2)2(NH3)2], is generated by inversion symmetry. The Ni(II) ion, which is located on an inversion center, has a distorted octa-hedral coordination environment and is surrounded by two ammine N atoms and two Cl atoms in the equatorial plane, with two N atoms of two imidazole groups occupying the axial positions. The imidazole ring makes a dihedral angle of 81.78â (18)° with the Ni/N/Cl equatorial plane. In the crystal, mol-ecules are linked via N-Hâ¯Cl hydrogen bonds and C-Hâ¯π inter-actions, forming a three-dimensional network.
