Crystal structure of fac-tricarbonyl(quinoline-2-carboxylato-κ²N,O)(triphenylarsane-κAs)-rhenium(I).

In the title compound, [Re(C10H6NO2)(CO)3{As(C6H5)3}], the coordination environment of ReI is that of a distorted octahedron. Three coordination sites are occupied by three carbonyl groups in a facial arrangement and the remaining three sites by triphenylarsane and deprotonated quinaldic acid in As-mono- and N,O-bidentate fashions, respectively. In the crystal, the complexes are linked through weak C--H···O hydrogen bonds, forming a three-dimensional network. It worth noting that, as far as we know, this complex is the first ReI triphenylarsane tricarbonyl compound to be reported. [ABSTRACT FROM AUTHOR]
