One of most inter­esting systems of coordination polymers constructed from the first-row transition metals is the porous ZnII coordination polymer system, but the numbers of such polymers containing N-donor linkers are still limited. The title double-chain-like ZnII coordination polymer, [Ag2Zn(CN)4(C10H10N2)2]n, presents a one-dimensional linear coordination polymer structure in which ZnII ions are linked by bridging anionic dicyanidoargentate(I) units along the crystallographic b axis and each ZnII ion is additionally coordinated by a terminal dicyanidoargentate(I) unit and two terminal 1-benzyl-1H-imidazole (BZI) ligands, giving a five-coordinated ZnII ion. Inter­estingly, there are strong inter­molecular AgI...AgI inter­actions between terminal and bridging dicyanido­argentate(I) units and C-H...[pi] inter­actions between the phenyl rings of BZI ligands of adjacent one-dimensional linear chains, providing a one-dimensional linear double-chain-like structure. The supra­molecular three-dimensional framework is stabilized by C-H...[pi] inter­actions between the phenyl rings of BZI ligands and by AgI...AgI inter­actions between adjacent double chains. The photoluminescence properties have been studied.

Experimental. Absorption correction: SADABS-2014/5 (Bruker,2014/5) was used for absorption correction. wR2(int) was 0.0492 before and 0.0423 after correction. The Ratio of minimum to maximum transmission is 0.9123. The λ/2 correction factor is 0.00150.

Geometry. 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.
