Abstract
The X-ray crystal structures of three halo(tetramethylethylenediamine)copper(I) complexes have been determined. (TMED)2Cu+CuCl −2 (I) crystallizes in monoclinic space groupP21/n with lattice constantsa=9.332(9),b=15.126(7),c=14.49(1) Å,β=96.95(7)°. (TMEDCuBr)2 (II) crystallizes in monoclinic space groupP21/c with lattice constantsa=12.064(5),b=11.888(6),c=15.841(6) Å,β=113.97(3)°. (TMED CuI)2 (III) crystallizes in monoclinic space groupP21/c with lattice constantsa=12.401(6),b=12.159(6),c=15.412(9) Å,β=109.12(4)°. Compound (I) is a molecule exhibiting two discrete environments for copper(I). The cation is a pseudotetrahedral monomer and the anion a linear monomer. Both (II) and (III) are dimers with asymmetrically bridging bromine and iodine atoms, respectively. Distortions from tetrahedral geometry are observed about the copper atoms in (II) and (III).
