| Abstract: | The title compound has been synthesized by the reaction of RuCl2-(PPh3)3], closo-B10H10]2- and PhCH(OH)COOH in (CH3)2CHOH solution. Crystalsof the title compound suitable for a single crystal X-ray diffraction analysis were recrystallized from n-pentane/CH2Cl2 solution. The crystal is monoclinic, space group P21,/n,Mr=1294. 19, with a=11. 591 (6), b=23. 993(4), c=24. 900(4) A, β=90. 52(2), V= 6925(4) A3, Dc= 1.241 g/cm3, Z=4, A(MoKa) =0. 71073 A, P=6. 2cm-1, F(000)=2640, R=0. 046, wR2=0. 083, S=1. 09. The cluster is a bimetallicspecies in which the second ruthenium center is bound exopolyhedrally to the compound{(PPh3)2RuB10H8OCH (CH3)2]2 } via an Ru (1) -C;(1)-Ru (2) bridge and Ru (2) B(6) and Ru(2)-B(7) bonds. |
