Syntheses of Two Chiral Clusters η5-C5H4C(NR)CH3-RuNiM(CO)5(μ3-S) (R = NH-C6H3-2,4-(NO2)2, M = Mo, 3;M = W, 4) and the Single-crystal Structure of Cluster 3

摘要

The new chiral clusters [η5-C5H4C(NR)CH3]RuNiM(CO)5(μ3-S) (R = NH-C6H3-2,4-(NO2)2, M = Mo, 3; M = W, 4) were synthesized and the structure of cluster 3 was determined by single-crystal X-ray analysis. Crystal data: C23H16O9N4MoNiRuS, Mr = 780.18, orthorhombic, space group Pbca with the following crystallographic parameters: a = 13.207(4), b = 16.036(5), c =25.513(8) (A), Z = 8, V= 5403(3) (A)3, Dc= 1.918 g/cm3,μ = 1.834 mm-1 and F(000) = 3072. The final R = 0.0512 and wR = 0.1132 for 2525 reflections with Ⅰ＞ 2.00σ(Ⅰ).
