Synthesis and Characterization of the Chiral Skeleton Cluster [NiRuMo(CO)_5(μ_3-S)(η~5-C_5H_5)(η~5-C_5H_4COCH_3)]

1 INTRODUCTION The chemistry of transition metal cluster has enjoyed an exceptional growth since the mid 1970s1, 2], especially in recent years the structural and bonding aspects of mixed-metal tetrahedral skeleton clusters have been extensively studied3]. One important reason is that such chiral cluster can induce an asymmetric catalysis potentially. In our research group, considerable efforts have been directed to the synthesis of chiral tetrahedral clusters containing four different…

Synthesis and Characterization of the Chiral Skeleton Cluster [NiRuMo(CO)5(μ3-S)(η5-C5H5)(η5-C5H4COCH3)]

The new chiral cluster NiRuMo(CO)5(μ3-S)(η5-C5H5(5-C5H4COCH3)] 3 was synthesized by the reaction of precursor CoRuMo(CO)8(μ3-S(η5-C5H4COCH3)] 1 with NiCp2 2 in refluxing THF. It was characterized by C/H elemental analysis, IR and 1H NMR. Molecular structure of cluster 3 was determined by single-crystal X-ray analyses. Crystal data: triclinic, space group Pī with the following crystallographic parameters: a = 7.9606(8), b = 8.5604(9), c = 14.779(2)A, = 93.908(2), = 105.057(2), = 101.463(2)°, C17H12O6MoNiRuS, Mr = 600.0(5), Z = 2, V = 945.5(2)A3, Dc = 2.108 g/cm3, = 2.568 mm-1, 2 max < 56.48, F000 = 584,the final R = 0.0380 and wR = 0.0674 for 2995 observed reflections with I>2.00σ(I).
