Reaction of(NH 4) 2MoOS 3 with CuBr and AgBr(molar ratio=1∶4∶1) in α-MePy produced dark red crystals of [MoOS 3Cu 4(α-MePy) 6Br 2]. The product was characterized by elemental analysis, IR and X-ray diffraction. It crystallizes in a triclinic system with space group P1 and unit cell parameters a=0.950 9(3) nm, b=1.066 8(2) nm, c=2.153 6(3) nm, α=94.846(9)°, β=92.054(7)°, γ=99.299(8)°, V=2.145 5(8) nm 3, Z=2, D c=1.828 g·cm -3, F(000)=1 168, μ=42.79 cm -1, R=0.049 and R w=0.051. The compound consists of a nido-shaped MoS 3Cu 3 cluster unit and a four-membered CuBrCuS ring by sharing the same Cu3—S3 bond. The Mo atom and the four Cu atoms adopt a distorted tetrahedral geometry coordination. The Mo…Cu1, Mo…Cu2 and Mo…Cu3 distances are 0.271 1(3), 0 269 8(2), and 0.268 1(1) nm, respectively.
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.
