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, the rmal 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. Ea ch 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 v ia H bonding interactions to generate a 2D network. It crystallizes in the monoc linic 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(F 2)=0.101 0, S=1.013.

The manganese(Ⅲ) complex [Mn (acacen) {N (CN)2}]n [H2acacen =bis (acetylacetone)ethylenediimine] has been synthesized and the structure has been determined. The complex forms a one-dimensional chain structure via the bidentate bridge ligandμ1,5-[N(CN)2]- linking [Mn(acacen)] moiety. The magnetic property of the compound (75~300 K) shows the existence of an antiferromagnetic exchange interaction among paramagnetic centers along the chain. CCDC: 244940.
