Abstract
The crystal structure of α-Bromo(2-dibutylaminoethanolato)copper(II) has been determined by single-crystal X-ray diffractometer methods using 1488 independent reflexions and MoKα radiation. The compound crystallized in the orthorhombic space group P212121 with four dimers in a unit cell of dimensions a = 21.235(13), b = 15.220(8) and c = 8.390(5) Å. The structure was refined by least-squares methods giving a final residue of R = 0.087. The dimer molecules with Cu-Cu-separations of 3.019(4) Å consist of nonplanar Cu2O2-rings with Cu-O-distances of 1.92(2) Å (mean value). The coordination around each copper atom is distorted square planar. The averaged Cu-N-distance is 2.06(2) Å and Cu-Br-separations are 2.333(4) A. In good agreement with the calculated density of 1.55 g cm-3 is the experimental value of 1.53(3) g cm-3.Keywords
