Abstract
The crystal structure of the title compound (NiC24H28O8N2) has been determined by X-ray diffraction methods in order to ascertain the positions of coordination of the nickel atom and the organic moiety. Crystals are triclinic, space group P[unk] with a = 8.309(1), b = 8.756(1), c = 10.600(1)Å, α = 99.21(1), β = 107.21(1), γ = 113.40(1)°, V = 641.3(2)Å3, Z = 1, D = 1.375 g·cm−3, λ (CuKα) = 1.5418 Å, μ = 14.77 cm−1, F(000) = 278, T = 293°K. The final R was 0.062 for 1548 observed reflections. The structure is monomeric with slightly distorted octahedral coordination geometry. The configuration is trans. The coordination of the polyketide moieties is established by the two ketonic oxygens. The nickel is center of symmetry.
