Abstract
The crystal structure of bisdiethylenetriaminecopper(II) bromide monohydrate has been determined by X-ray diffraction methods; refinement has been carried out by a full-matrix least-squares procedure with three-dimensional counter data. Z= 4 in the monoclinic unit cell, space group P21/c, with dimensions a= 13·903, b= 8·912, c= 14·207 Å, β= 101° 51′. Each diethylenetriamine (dien) ligand is tridentate, co-ordinating with the terminal nitrogen atoms trans to each other. The bonding of the dien ligands in the [Cu dien2]+ cation is not equivalent and the environment about the copper ion is the more usual tetragonally elongated octahedron. There are four approximately coplanar copper–nitrogen distances at 2·03–2·13 Å and two longer tetragonal distances at 2·35 and 2·46 Å(σ 0·02–0·03 Å).Keywords
