Unprecedented N,S,O co-ordination of the doubly deprotonated anion of N-benzoyl-N′-phenylthiourea (H2L2) bridging two rhodium(I) centres: crystal structure of the acetone solvate of [(PPh3)2(CO)Rh(μ-L2-κN′∶κO,S)Rh(PPh3)(CO)]

Reaction of [Rh(CO)2Cl]2 with N-benzoyl-N′-phenylthiourea (H2L2) followed by PPh3 resulted in an unprecedented tridentate (κN′∶κO,S) bonding mode of the doubly deprotonated anion of N-benzoyl-N′-phenylthiourea to yield a dinuclear rhodium(I) complex [(PPh3)2(CO)Rh(µ-L2-κN′∶κO,S)Rh(PPh3)(CO)]·(CH3)2CO, the structure of which was determined by X-ray crystallography.
