✦ Synopsis
Tungsten and molybdenum complexes [M(CO)
2 -(dpphen)(dbf) 2 ] (M = W 1 or Mo 2; dpphen = 4,7-diphenyl-1,10-phenanthroline; dbf = dibutylfumarate) have been synthesized and structurally characterized by X-ray diffraction analysis. In both complexes which have similar structure, the metal atom co-ordination is distorted octahedral with dpphen and two CO groups in the equatorial plane and the metal atom binds in an g 2 -fashion to the C±C bonds of two dbf ligands. The two C±C bonds are almost mutually orthogonal. The two complexes are different in conformation which result from face selection of the two dbf ligands for coordination to the metal atom.
