The synthesis and crystal structures of dinuclear copper(I) complexes [Cu2(μ-SR)(μ-PNP)Br] [R = Ph (4), CH2Ph (5); PNP = 2,6-bis(di-tert-butylphosphinomethyl)pyridine] in which both the thiolate and PNP act as bridging ligands are described. The PNP ligand bridges in an unprecedented κ2-P,N-κ1-P mode. The Cu…Cu distance of 2.7 Å, DFT calculations for optimized mol. structure, topol. anal. of electron d. in the framework of quantum theory of atoms in mols. (QT AIM) and natural-bond-order (NBO) anal. all indicate the absence of metallophilic interactions. These dinuclear complexes were prepared by treating a coordination polymer [Cu2(μ-PNP)(μ-Br)2]n (3Br) with NaN(TMS)2 followed by the thiol (HSR). The synthesis of the precursor 3Br from PNP and [CuBr(SMe2)] is also described. The crystal structure of the related μ-chloro complex (3Cl) was determined since the μ-bromo complex formed poor quality crystals. Preliminary reactivity studies showed that the bromide ligand in complex 5 can be substituted with NCS or SPh.
