Synthetic and structural studies on organotransition metal–bismuth nitrates
Abstract
The reaction between Bi(NO3)3·5H2O and 2 equivalents of K[Fe(CO)2(η-C5H5)] affords the iron–bismuth complex [Bi(NO3){Fe(CO)2(η-C5H5)}2]1 which was characterised by X-ray crystallography. Complex 1 comprises a bismuth atom in a trigonal-pyramidal co-ordination geometry bonded to two Fe(CO)2(η-C5H5) fragments and the oxygen atom of a monodentate nitrate group. In addition there is a longer secondary intermolecular contact between the bismuth and a nitrate oxygen of an adjacent molecule which is approximately trans to the primary Bi–O bond. The complexes [Bi(NO3)(MLn)2][MLn= Fe(CO)2(η-C5H4Me)2, Ru(CO)2(η-C5H5)3, Mo(CO)3(η-C5H5)6, Mo(CO)3(η-C5H4Me)7, W(CO)3(η-C5H5)8, W(CO)3(η-C5H4Me)9 or Cr(CO)3(η-C5H5)10] have also been prepared and characterised by spectroscopic and analytical methods. Data are also presented on the synthesis and characterisation of the ruthenium complexes [Bi{Ru(CO)2(η-C5H5)}3]4 and [BiCl{Ru(CO)2(η-C5H5)}2]5 and on the reactions between bismuth nitrate and 2 equivalents of K[Mn(CO)5] or K[Co(CO)3(PR3)](R = Ph or OPh).
