Dimolybdenum Complexes with a Potentially Tetradentate PNNP Ligand,2,7-Bis(diphenylphosphino)-1,8-naphthyridine (dpnapy)
Abstract
Reaction of cis-[Mo2(O2CCH3)2(CH3CN)6](BF4)2 with a potentially tetradentate PNNP ligand, 2,7-bis(diphenylphosphino)-1,8-naphthyridine (dpnapy), in a 1:2 molar ratio afforded a mixture of isomeric dimolybdenum complexes, cis-[Mo2(O2CCH3)2(dpnapy-N,P)2](BF4)2 (1) and trans-[Mo2(O2CCH3)2(dpnapy-N,N′)2](BF4)2 (2) in 63 and 5% yields, respectively, which were characterized by X-ray crystallography.
