- Abstract
The crystal and molecular structure of a macrocyclic oxamido Schiff base Ni(II) complex [NiL] has been determined by X-ray crystallography. L is the dianion of diethyl 5,6,7,8,15,16-hexahydro-6,7-dioxodibenzo[1,4,8,11]tetraazacyclotetradecine-13,18-dicarboxylate. Ni(II) is located in the coordination cavity formed by the four nitrogen donors of the deprotonated macrocyclic oxamido ligand with a distorted square-planar geometry. C–H ⋅ ⋅ ⋅ O hydrogen bonds have been observed in the crystal. The macrocyclic complex crystallizes in the triclinic space group P − 1, with lattice parameters a = 7.977(3) Å, b = 12.581(4) Å, c = 12.679(4) Å, α = 112.669(6)°, β = 96.849(7)°, γ = 106.204(7)°, V = 1089.9(6) Å3, Z = 2.
