Fecha de publicación: | 1994 | Editor: | Elsevier | Citación: | Inorganica Chimica Acta 216(1-2): 185-190 (1994) | Resumen: | The crystal and molecular structure of a new tetracarboxylato-bridged copper(II) dimer, the bis(dimethyl sulfoxide)tetrakis(μ-formato)dicopper(II) has been determined by X-ray diffraction methods. It crystatlizes in the tetragonal space group I41/a, with Z=8 in a cell of dimensions a=17.688(2), c=10.408(1) Å. The structure is built up of centrosymmetric neutral dimers [Cu2(HCOO)4(dmso)2], where four bidentate carboxylate anions form syn-syn bridges between the metal atoms which are in a 4 + 1 environment. Magnetic susceptibility data show that the copper atoms are strongly antiferromagnetically coupled with J=-434 cm-1. The obtained triplet-singlet energy gap is compared with those reported for a series of related dimers. Finally, the ESR spectrum shows characteristic features of a triplet state with a non-negligible zero field splitting, being typical of the copper(II) dimeric tetracarboxylates. | URI: | http://hdl.handle.net/10261/129815 | DOI: | 10.1016/0020-1693(93)03728-S | Identificadores: | doi: 10.1016/0020-1693(93)03728-S issn: 0020-1693 |
