Title: Bonding of eta/sup 2/-sulfur dioxide: structures of tricarbonyl(1,10-phenanthroline) (eta/sup 2/-sulfur dioxide)molybdenum(0) and dicarbonyl(2,2'-bipyridyl)bis(eta/sup 2/-sulfur dioxide)molybedenum(0)

Abstract

The structures of the title complexes have been determined by X-ray diffraction techniques. Tricarbonyl(1,10-phenanthroline)(eta/sup 2/-sulfur dioxide)molybdenum(0) crystallizes in the space group C2/m with cell constants of a = 19.206 (5) A, b = 12.695 (2) A, c = 8.025 (1) A, ..beta.. = 129.00 (5)/sup 0/ and refines to an unweighted R value of 3.4% on the basis of 945 observations. Dicarbonyl(2,2'-bipyridyl)bis(eta/sup 2/-sulfur dioxide)molybdenum(0) crystallizes in P anti l with cell parameters of a = 11.070 (5) A, b = 7.096 (1) A, c = 11.043 (6) A, ..cap alpha.. = 111.97 (2)/sup 0/, ..beta.. = 98.25 (4)/sup 0/, and ..gamma.. = 100.02 (3)/sup 0/. Full-matrix refinemwnts based on 1190 observations resulted in an R value of 3.0%. Both structures contain eta/sup 2/-type Mo-SO/sub 2/ linkages. The first of these complexes exhibits Mo-O and Mo-S distances of 2.223 (7) and 2.532 (3) A with dihedral angle between the SO/sub 2/ and c-MSO/sub M/ planes of 108.1/sup 0/. The SO/sub 2/ is trans to a carbonyl. The corresponding distances in the trans-(SO/sub 2/)/sub 2/ complex are 2.113 (4) and 2.109 (4) A for Mo-O and 2.496 (3) A for both Mo-S distances with dihedral angles of 103.6 and 103.3/sup 0/, respectively.more » The two bound S-O bonds are perpendicular to one another and are in the same plane with a cis carbonyl. The eta/sup 2/-SO/sub 2/ bonding is discussed in relationship to these structures.« less
