Synthesis and crystal structure of a ruthenium complex containing two monodentate DPPM ligands (DPPM = bis(diphenylphosphino)methane)
摘要:
The compounds trans-Ru(quin)2(dppm)2 and cis- and trans-Ru(quin)2(PPh3)2 (quin=2-quinaldinate anion; dppm=bis(diphenylphosphino)methane) have been prepared by the reaction of RuCl3.3H2O and Hquin, in basic alcoholic medium, in the presence of dppm and PPh3, respectively. The compounds are characterized by elemental analysis, IR, H-1 and P-31{H-1} NMR spectroscopy. The structure of trans-Ru(quin)2(dppm)2.2MeOH has been determined by X-ray crystallography. The compound has two bidentate N,O-quinaldinate and two monodentate dppm ligands in a trans-N, trans-O, trans-P arrangement.
