| Synthesis of Novel Tetracarboxylato Dirhenium(III) Compounds and Crystal Structure of [Re2 (l-Adamantylcarboxylate)4Cl2] * 4 CHC13  | | | | Abstract
| The coordination compounds o f the general formula Re2 (1^ 4X2 (X = Cl, Br; L = 1 -adamantyl-carboxylate and 1 -adamantylacetate) have been prepared and characterized by means of UV-VIS spectroscopy (20000 cm-1 , 6 —► 6*). The crystal and molecular structure of Re2(AdCOO)4Cl2 • 4 CHCI3 solvate was determined by X-ray diffraction. The units Re2(AdCOO)4Cl2 adopt a centrosymmetric dinuclear array with each metal atom coordinated in a distorted octahedron comprising one rhenium and one chlorine atoms (Re-Cl 2.505(2) A) and four carboxylate oxygen atoms in the equatorial plane. The rhenium-rhenium separation of 2.2300(5) A corre sponds to quadruple bond between the metal atoms. All R e-0 bonds have an almost uniform length (2.017(4) -2.032(4) A) and do not differ essentially from the parameters reported for related compounds. The closest environment of the Re2(AdCOO)4Cl2 molecules in the crystal comprises weak Cl— HC hydrogen bonds with the chloroform molecules and significantly shortened van der Waals contacts Cl— Cl, 3.46 A. | | | |
