Molecular and Supramolecular Structures of a Nickel( Ⅱ ) Complex with a Macrocyclic Ligand |

| Abstract: | The crystal structure of the title complex, NiL], has been determined by using X-ray analysis (H2L = 2,3-dioxo-5,6:13,14-dibenzo-7,12,bis(methoxycarbonyl)- 1,4,8,11 -tetraazacyclotetradeca-7,1 1-diene). Crystal data: C22H18N4O6Ni, Mr = 493.11, triclinic, space group P1-, a = 9.128(6), b= 9.941(7), c = 12.396(8)(A), α = 107. 11(1), β= 106.14(1), γ= 97.69(1)°, V = 1003.9(11)(A)3, Z = 2,Dc = 1.631 g/cm3,μ(MoKtα) = 1.018 mm-1, F(000) = 508, R = 0.0584 and wR = 0.0981 for 1724 observed reflections with Ⅰ＞ 2σ(Ⅰ). The Ni(Ⅱ) atom is coordinated by four nitrogen donors of the macrocyclic ligand with a slightly distorted square-planar geometry. In the crystal, the C-H…O hydrogen bonds link the complex molecules to form infinite 1D chains which are further linked by π…π stacking interactions to form chain-pairs. |
