摘要:
The crystal structures of chloro(eta(5)-cyclopentadienyl)-[methylenebis (diphenylphosphine-P)]ruthenium-chloroform (1/1), [RuCl(C5H5)(C25H22P2)].CHCl3, (A), and chloro(eta(5)-cyclopentadienyl)[1,2-ethanediylbis(diphenylphosphine-P)]ruthenium-chloroform (1/1), [RuCl(C5H5)(C26H24P2)].CHCl3, (B), are reported. Both complexes contain a central ring structure in which a pair of P atoms, linked by a -CH2- [in (A)] or a -C2H4- [in (B)] group, are bonded to a central Ru atom. The P-Ru-P bond angle undergoes expansion from 72.07 (2)degrees in (A) to 83.48(2)degrees in (B). The bond distances around the Ru center are compared with values reported for similar compounds. Both structures include a chloroform solvent molecule in addition to the ruthenium complex. The chloroform molecule in (A) was found to be disordered.
