A new complex [Ag4(μ2-S-mbo)4(dppp)4](1) is obtained from the reaction of AgBF4 and Hmbo(2-mercaptobenzoxazole) with the participation of dppp(bis(diphenylphosphino) propane). Single crystal X-ray diffraction analysis shows that it is discrete neutral molecule and composed of two asymmetrical moieties. Four Ag atoms in each molecule are completely coplanar and of similar environment. The ligands Hmbo and dppp in complex 1 bridge two Ag atoms through “μ2-S-mbo” and P atoms in two ends, respectively. The possible mechanism of the reaction is provided, and the sequence of adding materials and the length of backbone (CH2)n in diphosphine play an important role in the results of the reactions.
