Poly[[μ2-1,2-bis(diphenylphosphanyl)-1,2-diethylhydrazine]-μ4-nitrato-μ2-nitrato-silver(I)]

Abstract

The title compound, [Ag2(NO3)2(C28H30N2P2)]n, crystallizes in polymeric α-helices. Three O atoms from three different nitrate ions in equatorial positions and two Ag atoms at axial positions set up a trigonal bipyramid. These units are linked by the phosphine ligands into endless helical chains that run along the c axis. The crystal used for the data collection was a racemic twin.
