The structure of the gel-grown coordination polymer Ag-4 (2,2-dimethylglutarate)(2) was determined by X-ray crystallography. It crystallizes in the monoclinic space group P2(1)/a, with a = 10.67(1) Angstrom, b = 6.334(6) Angstrom, c = 13.32(1) Angstrom, beta = 96.34(4)degrees, V = 895(2) Angstrom(3) and Z = 4. The structure is based on an unusual oligomeric unit, which was first found in silver(I) glutarate, and consists of a planar, centrosymmetric, tetranuclear silver cluster coordinated by two bridging ligands disposed at both sides of the metal plane. Additional Ag-O coordination bonds link the units together in a 2-D framework. Short metal-metal contacts in the range 2.81-3.40 Angstrom, are observed within the layers, suggesting that d(10)-d(10) interactions contribute to the stabilization of the structure.
