Abstract
The crystal structure of dichloro-(N,N,N′,N′-tetramethylethylenediamine)zinc(II), C6H16Cl2N2Zn, has been determined from 1684 reflexions measured on a Siemens four-circle diffractometer (A.E.D.) using the ω/2θ-scan technique and CuKα radiation. The crystals are monoclinic, space groupP21/c,a = 7·716(3),b = 13·335(9),c =11·545(5) Å, β = 105·59(6) ° andZ = 4. The structure was solved by Fourier methods, and refined by full-matrix least squares to a finalR (conventional) of 6·7 %. Anisotropic thermal parameters were evaluated for the non-hydrogen atoms, but the hydrogen atoms were assigned the equivalent isotropic thermal parameters of the carbon atoms to which they were bonded. The geometry around the zinc atom is distorted tetrahedral, with the Zn-Cl and Zn-N average bond lengths of 2·207(4) and 2·08(1) Å respectively.
