Structural study of hexacarbonyldi-μ-mercaptobenzothiazolato(μS,N) dimanganese

The structure of hexacarbonyldi--mercaptobenzothiazolato(S,N)dimanganese, Mn(CO)₃mbt]₂, has been solved using three-dimensional X-ray data. The compound crystallizes in the space groupC2/c, with unit-cell constantsa = 14.38(2),b = 11.84(2),c = 13.90(2) Å, and = 94.70(8) °. Least-squares refinement of the positional and anisotropic thermal parameters gives a finalR value of 0.048 for 2090 independent reflections. The results are compared with those obtained with the previously reported isomorphous complex of rhenium, and the structural arrangement is discussed in terms of metalic corrosion inhibition.Equipe de Recherche Associée au C.N.R.S.
