catena-Poly[[(N,N-dimethylformamide-κO)(nitrato-κO)silver(I)]-μ-1,2-bis(diphenylphosphino)ethane-κ2P:P′] at 100 and 293 K: temperature effects on the volume of the solvent pocket

catena-Poly[[(nitrato-κO,O')silver(I)]-μ-1,2-bis-(diphenyl-phosphino)ethane-κP:P']

In the title chain compound, [Ag(NO₃)(C₂₆H₂₄P₂)]_n, the bis­(diphenyl­phosphino)ethane (dppe) units link the Ag⁺ ions into chains along [001]. A nitrate anion is coordinated to the Ag atom. There is a centre of symmetry at the mid-point of the ethane C—C bond and a twofold rotation axis passes through the Ag, N and terminal O atoms. Each Ag atom is four-coordinated in a distorted tetra­hedral geometry by two O atoms of the nitrate anion and two P atoms of dppe ligands. The two aromatic rings are oriented at a dihedral angle of 73.77 (3)°.
