Abstract
Abstract Two new silver(I) complexes containing dppm, nitrogen heterocyclic ligands and sulfate anions, namely [Ag2(μ-dppm)2(μ-SO4)(2-amp)2]·CH3OH (1) and [Ag4(μ-dppm)2(μ-SO4)2(μ-4,4′-bpy)2]·2CH3OH (2) (dppm = bis(diphenylphosphino)methane, 2-amp = 2-aminopyrimidine, 4,4′-bipy = 4,4′-bipyridine), have been synthesized and characterized by IR, X-ray crystallography, luminescence, 1H, 31P NMR spectroscopy. In complex 1, [Ag2(μ-dppm)(μ-SO4)(2-amp)2] binuclear units are linked through robust hydrogen-bond synthon R 2 2 ( 8 ) to give rise to a 1D polymer. While in complex 2, two [Ag2(μ-dppm)(μ-SO4)] units are linked together to form a tetranuclear cluster by two 4,4′-bipyridine ligands.
