Synthesis and crystallographic structure of substituted dodecacarbonyltriruthenium by heptene hydride cluster H~3Ru~3(CO)~9(C~7 H~1~1)

Substitution of Ru3(CO)12 by heptene gave H3Ru3(CO)9(C7H11). The structure of the product is speculated by the anal. of IR, 1H NMR, 13C NMR, MS and elementary anal. The double bond in heptene was opened. An x-ray diffraction of the product has unequivocally established its structure. The cluster is triclinic space, and the space group is P1. a 0.9726(2) nm, b 0.9868(1) nm, c 1.1104(2) nm, a 103.22(1), b 89.91(1), g - 91.55(1)? Z = 2, m = 21.59 cm-1, dc = 2.09 g/cm3, F (000) = 628, R = 0.0371.
