| Abstract: | Crystal structure of nickel(Ⅱ) complex with a new mesocyclic diamineligand, 3-hydroxy1-1, 5-diazacycloheptane, C10H24N41NiO2Br2. 2H2O, Mr=486. 9 is reported. It crystallizes in monoclinic P21/c with a=7. 167 (1 ), b=13. 794 (3 ), c =9. 726 (3),β=109.42(2)°, V= 906. 8 (4) , Z= 2, Dc= 1.783g/cm3, μ=5. 477mm-1, F(000) =492. The final R and Rw are 0.045 and 0.045 for 1155 observedreflections with I≥4. 0σ(I). The result of X-ray structure determination shows thatnickel (Ⅱ) forms an octahedral bicyclic complex with 3-hydroxy1-1, 5-diazacycloheptane. |
