 Title    Direct Synthesis of Tetranuclear Complexes of Copper(II) with /i4-Bridging Oxygen  
 Abstract    The direct synthesis of a num ber complexes with general composition Cu4OCl6 «(CH 3)2NH-raSolv, where n = 4, m = 0 -2 and Solv = C H 3OH, DMSO, is reported. It is shown by X-ray structure investigation, that in Cu4OCl6-4 (C H 3)2N H the copper atoms are linked by //4-oxygen and //2-chlorine bridging atoms, while molecules of (CH3)2NH are at­ tached to the metal atoms via nitrogen ones.

 Title    Crystal Structure of the Di-bromo-bis(2-dimethylaminoethanolato)(dime- thylsulfoxide)-copper(II)-lead(II) Dimer Obtained by Direct Synthesis  
 Abstract    A heterotetranuclear C unPbu complex containing 2-dimethylaminoethanol has been synthesized, using copper powder and PbB n as starting materials, and character­ ized by X-ray crystallography. The crystal is composed of centrosymmetric molecules [C uP b B ^ K C H ^N C F b C F L O j^ d m so h . The central strictly planar fragment is a Pb2Ü2 paral­ lelogram completed by bridging oxygen atoms of chelating 2-dimethylaminoethoxo groups. The Pb atom forms four quite short bonds with oxygen atoms of the three 2-dimethylaminoethoxo groups and of the dmso molecule and assumes a six-coordinate structure also involving two bromine atoms. The two oxygen and two nitrogen atoms of two 2-dimethylaminoethoxo groups form the copper coordination environment, which possesses a somewhat distorted square planar geometry.
