Abstract
The synthesis, optical, magnetic properties and X-ray crystal structure of [Cu(dmbipy)(OH)(CF3SO3)](2) (in which dmbipy = 4,4'-dimethyl-2,2'-bipyridin e) is described as a new dinuclear hydroxo bridged copper(II) compound with a Cu-O-Cu angle of 94.5(3)degrees and a strong ferromagnetic interaction h aving an exchange parameter J of 148 cm(-1) (singlet above the triplet grou nd state). The Cu-O-Cu angle is the smallest observed so far for hydroxo-br idged compounds. (C) 2001 Elsevier Science B.V. All rights reserved.
