metal-organic compounds
The title compound, [{Cu(C3H4N2)4}(Cr2O7)]n, containing a [Cr(Him)4]2+ cation (Him = imidazole) and a dichromate anion, was obtained by hydrothermal synthesis. Each Him ligand coordinates to the Cu atom via one N atom, forming a tetragonally elongated octahedral geometry with a basal plane defined by four coplanar imidazole N atoms, the axial sites being occupied by O atoms from two dichromato ligands. The dichromate anions bridge the Cu ions to form one-dimensional zigzag chains.
