چکیده
In the title compound, C(22)H(24)N(4)O(2)S(2), the two thio-urea segments of the side-arm groups are inclined at a dihedral angle of 73.09 (9)°. The central cyclo-hexane bridge adopts a chair conformation. The mol-ecule is stabilized by N-H⋯O intra-molecular hydrogen bonds forming S(6) rings, and N-H⋯O and N-H⋯S inter-molecular hydrogen bonds forming infinite chains developing parallel to the b axis.

The crystal structure of a racemic mixture of the title ruthenium(II) complex, [RuCl(C(30)H(30)O(2)P(2))(2)]CF(3)SO(3)·2CH(2)Cl(2), reveals that the coordination geometry about the coordinatively unsaturated metal centre is approximately trigonal-pyramidal, with the chlorine atom occupying one of the equatorial positions. The axial Ru-P bonds are longer than the equatorial Ru-P bonds and there ...
