CRYSTAL-STRUCTURE OF (2)(PPH(2)(O-TOL))CL][CLO4]CENTER-DOT-1.5(CH2CL2), A STRUCTURE CONTAINING BOTH ORDERED AND DISORDERED DICHLOROMETHANE MOLECULES OF CRYSTALLIZATION

The complex cis-[Ru(bpy)(2) {PPh(2)(o-tol)}Cl][ClO4] crystallizes from dichloromethane as the sesqui-dichloromethane solvate, The complex cr ystallizes in the monoclinic space group P2(1)/n with Z = 4. The struc ture was refined to R = 5.50% for those 2552 independent reflections w ith \F-o\ > 6 sigma(\F-o\). The octahedral Ru(II) cation is associated with the following bond lengths: Ru-PPh(2)(o-tol) = 2.360(3)Angstrom, Ru-Cl = 2.433(2)Angstrom and Ru-N(bpy) = 2.041(8)-2.095(8)Angstrom. B oth the perchlorate anion and the dichloromethane molecules of solvati on exhibit large amplitudes of vibration. One dichloromethane molecule lies in a general position, the other lies about an inversion center and suffers from disorder.
