catena-Poly[[(benzyldiphenylphosphine-κP)silver(I)]-μ-nitrato-κ2 O:O′-[(benzyldiphenylphosphine-κP)silver(I)]-μ-nitrato-κ4 O,O′:O′,O′′]

The title silver(I) benzyldiphenylphosphine complex crystallizes as a one-dimensional chain propagating through nitrato anions bound to each adjacent silver cation via both bis-monodentate and bis-bidentate coordination.

The structure of the title complex, [Ag 2 (NO 3 ) 2 (C 19 H 17 P) 2 ] n , reveals a chain emanating from the coordination of one phosphine ligand to each silver(I) cation, as well as the bis-monodentate coordination of a bridging nitrato ligand (per Ag atom) and the bis-bidentate coordination of another bridging nitrato ligand (per Ag atom). The distorted four-coordinate Ag atoms are characterized by bonding angles that notably deviate from the ideal tetrahedral shape.
The inorganic polymer packs in three dimensions as layers of one-dimensional ribbons when viewed along the b axis (Fig. 2); the chain has glide symmetry. Furthermore, the aromatic rings of the phosphine ligands then overlap in an adjacent layer to form a hydrophobic layer in between Ag-NO 3 -containing layers.

Synthesis and crystallization
Benzyldiphenylphosphine (1 mmol) was dissolved in acetonitrile (10 ml). Silver nitrate (1 mmol) was dissolved in acetonitrile (10 ml). In order to obtain the given 1:1 molar ratio, the solutions were mixed. The resulting solution was heated to 353 K for approximately 2 h. The solution was removed from the heat and left to slowly cool. During the process of the slow evaporation of the solvent, clear colorless crystals started to form.

Refinement
Experimental details including crystal data, data collection and structure refinement details are summarized in Table 1. The highest calculated residual electron density peak is 2.51 e À Å À3 and is located 0.99 Å from Ag2, which is attributed to the presence of the strong absorber (Ag), as well as imperfections in the absorption correction process.

All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. Refinement.
