A new perspective on vanadyl tartrate dimers. Part II. Structure and spectroscopic properties of calcium vanadyl tartrate tetrahydrate
- Universidad del Pais Vasco, Bilbao (Spain)
The calcium vanadyl tartrate complex [Ca(VO)(d,l-C{sub 4}H{sub 2}O{sub 6})(H{sub 2}O){sub 4}] has been synthesized and characterized by spectroscopic methods. Its crystal structure was solved by X-ray metods. The compound is monoclinic, space group P2{sub 1/c}, with a = 8.0282(5), b = 17.1568(8), c = 7.6113(3) {angstrom}, {beta} = 94.269(4){degrees} and Z = 4. The structure consists of centrosymmetric vanadyl tartrate dimers, [(VO)(d,l-C{sub 4}H{sub 2}O{sub 6})]{sup 4{minus}}{sub 2}, and calcium cations placed between them. As a result, dimers form chains in the [101] direction. Neighbouring chains are linked by the coordination of the calcium ion to the oxygen atom of a vanadyl group of a different chain, thus forming a two-dimensional structure. Different layers are linked by hydrogen bonds. Spectroscopic studies show the existence of intra-dimeric interactions between vanadium atoms. 23 refs., 4 figs., 5 tabs.
