摘要：
The complex [Ag(DDM)2(CH3C6H4NH2)]NO3, where DDM is 4,4-diaminodiphenylmethane [CH2(C6H4NH2)2], was synthesized and its structure was determined. The crystals are monoclinic, space group P21/n, a = 9.543(2) Å, b = 18.056(4) Å, c = 1.901(2) Å, β = 106.94(3)°, V = 1796.8(6) Å3, ρcalcd = 1.443 g/cm3, Z = 4. The Ag atom (at the inversion center) is coordinated at the vertices of an almost undistorted octahedron by six nitrogen atoms of the primary amino groups from four bridging DDM molecules and two terminal p-toluidine molecules (Ag-N, 2.546(3) Å; NAgN, 89.7–90.3°). Wavelike layers composed of conjugate multiunit metal rings, each containing four Ag+ ions and four bridging DDM ligands, are formed in the structure in the [101] direction (a 2D polymer). Uncoordinated NO3− anions are arranged in the cavities between the layers and link them by N-H⋯O hydrogen bonds.
