A mixture of 38 mg (0.37 mmol) Pd2(dba)3CHCl3, 100 mg (0.74mmol) of [Mo3S4Cl3(dbbpy)3]Cl and 56 mg (0.74 mmol) of thioureain 20 ml of dichloromethane was refluxed for 5 hours. An excess ofhexane was layered onto the resulting brown solution to givegreenish-brown crystals of 2. Yield: 80 mg (71percent). Anal. Calcd forC55H76N8Cl4Mo3S5Pd: C 42.7, H 5.0, N 7.2, S 10.4.
