Abstract
Pyrolysis of solutions containing [{P(OMe)Ph2}3RuCl3Ru{P(OMe)Ph2}3]Cl for 12 h at 120 °C gives yellow crystals (1) shown by X-ray diffraction analysis to be [{P(OMe)Ph2}2{P(OH)Ph2}RuCl3Ru{P(OH)Ph2}2(Ph2PO)]. The crystals are monoclinic, space group P21/c with a= 13.19, b= 21.98, c= 24.98 Å, β= 109.40°, and contain one molecule per asymmetric unit. The structure was solved using 1 534 film data, and refined to R 0.11. Related pyrolysis reactions give the compounds [{P(OEt)Ph2}2{P(OH)Ph2}RuCl3Ru{P(OH)Ph2}2(Ph2PO)](2) and [{P(OEt)Ph2}2{P(OH)Ph2}RuBr3Ru{P(OH)Ph2}2(Ph2PO)](3).Keywords
