The complex crystallizes in space group P21/c with Z=4. The cell dimensions are=8.255(3),b=17.951(6),c=16.541(4) Å, and β=91.03(2)°. Least-squares refinement of the structure has yielded a final R value of 4.52% for 2108 independent reflect ions. The square pyramidal structure consists ofN, N, N', N'-tetramethylethylenediamine and twoN-methylformamide ligands forming a basal square plane with Cu−N bond lengths of 2.029(5) and 2.033(5) and Cu−O 1.981(4) and 1.985(4) Å, and a thirdN-methylformamide on the apex with a Cu−O distance of 2.181(4)Å. Each of the molecular plances of the three N-methylformamides lies nearly coplanar with thexy, yz andxz molecular coordination planes. The bonding properties of the title compound and its i.r. and uv-vis spectra are discussed with reference to the structure.
