The crystal (C40H40F12MnN16O4P2, Mr = 1153.76) belongs to the triclinic system, space group P with the following crystallographic parameters: a = 10.761(2), b = 11.040(2), c = 23.365(4) ? a = 85.52(1), b = 82.69(1), g = 70.44(1)? V = 2592.5(8) 3, Dc = 1.478 g/cm3, m(MoKa) = 4.16 cm-1, F(000) = 1174, Z = 2, final R = 0.0493 and wR = 0.1158 for the observed reflections (I > 2.00s(I)). The X-ray analysis revealed that manganese(Ⅱ) cation coordination environment is a distorted octahedral geometry, and the Mn2+ cation is coordinated by four oxygen atoms of water in the equatorial plane, while the two nitrogen atoms of 3, 3?azpy occupy the axial positions. The complex forms a one-dimensional chain structure via 3, 3?azpy bridging ligand.展开更多

It crystallizes in triclinic, space group P with a = 9.1617(16), b = 10.5894(17), c = 11.957(2) ? a = 85.789(6), b = 89.395(7), g = 82.503(6), V = 1147.0(3) ?, Z = 1, C50H62N4O4Sm2, Mr = 1083.74, Dc = 1.569 g/cm3, F(000) = 546 and m(MoKa) = 2.583 mm-1. The structure was solved by direct methods and refined by full-matrix least-squares techniques. The final R and wR are 0.0271 and 0.0637, respectively for 4963 independent reflections. Each samarium atom is involved in two single bonds (one to each N2Ph2 unit) and two donor bonds (one to each N2Ph2 unit).展开更多

X-ray analysis reveals that the Cu atom adopts a distorted octahedral (4 + 2) coordination. The four closer donor atoms include two N atoms of 3,3?azpy and two O atoms of the coordination aqua with the CuN and CuO distances of 2.014(3) and 1.974(3) ? respectively. Two longer out-of-plane CuO bonds (2.450(3) ? from nitrate complete the strongly distorted octahedral coordination of the Cu atom. Hydrogen bonds are formed through H atoms of each coordination aqua with the remaining N atoms of 3,3?azpy and O atoms of nitrate. A two-dimensional network is constructed by hydrogen bonds and p-p interactions.展开更多
