Diphosphino organochalcogenide metal complexes have been investigated presently fortheir possible use as anti-cancer agents[1-3]. However, the area of silver complexes withmixed phosphine-thiolato ligands has scarcely been touched[4]. As a heterocyclic thiolato lig-and with potential S and N donors, 2-mercaptobenzoxazole (Hmbo) is interesting because ofthe structural chemistry of its multifunctional coordination modes (unidentate-N, unidentate-S or bidentate-N : S)[5-8]. Until now, Ag-mbo complex has been unknown to our knowl-edge, despite the fact that its complexes of Sn[5] , Au[6] and Li[7,8] have been reported. Hereinwe report the X-ray crystal structure of a self-assembled coordination polymer[Ag2(μ2-dppe)3(S-mbo)2]n · 2nDMF(dppe=1,2-bis(diphenylphosphino)ethane, Hmbo=2-mercaptobenzoxazole, DMF = dimethyl formamide).
