| Abstract: The title compound [Ni(acac)2(dadpm)]∞ (acac=acetylacetonate, dadpm=4,4′-diaminodiphenylmethane) was synthesized from Ni(acac)2·2H2O with dadpm in DMF. The structure was characterized by elemental analysis, IR spectroscopy, thermal analysis and single-crystal X-ray diffraction. X-ray analysis revealed that the central Ni atom is at a center of symmetry, and is octahedrally coordinated by four O atoms from two acac anions and two N atoms from two dadpm ligands. Each dadpm ligand, which has a two-fold axis passing through its methylene C atom, bridges two Ni atoms to form a 1D polymeric chain. Neighboring chains connect via H bonding interactions to generate a 2D network. It crystallizes in the monoclinic system, space group P2/c with a=0.556 79(7), b=0.896 06(12), c=2.187 3(3) nm, β=94.942(3)°, V=1.087 2(3) nm3, Z=2, Dc=1.390 g·cm-3, F(000)=480, Mr=455.17, μ(Mo Kα)=0.924 mm-1, R(F)=0.036 0, wR(F2)=0.101 0, S=1.013.
