Abstract
The crystal structure of bis(diethylenetriamine)copper(II) nitrate has been determined by X-ray diffraction methods and refined by full-matrix least-squares procedure. The orthorhombic unit-cell (space group P212121) has dimensions a= 9·274, b= 12·192, c= 15·029 Å, for Z= 4. Each diethylenetriamine ligand is tridentate, coordinating with the terminal nitrogen atoms trans to each other. The environment about the copper ion is a tetragonally distorted octahedron of a compressed form. The average lengths of the in-plane and tetragonal copper–nitrogen bonds are 2·22 and 2·01 Å with an estimated standard deviation of 0·010–0·015 Å. The symmetry of the cation is C2.Keywords
