Abstract:

The two allomers of the title complex of [pentanetrione 2, 4-bis(salicylhydrazonato)] nickel (II), Ni1C19H 16N4O5, crystallize in the monoclinic system, and space group C2/c, a = 1.03076(9) nm, b = 1.9105(1) nm, c = 0.93305(8) nm, β = 101.490(4)°, V = 1.8006(3) nm3, Dc = 1.620 g · cm-3, Z = 4, F(000) = 904, μ = 1.119 mm-1, R = 0.0370, GOF = 0.748 (crystal 1); a = 2.1949(3) nm, b = 0.9901(2) nm, c = 0.8568(1) nm, β = 92.799(6)°, V = 1.8597(5) nm3, D c = 1.568 g · cm-3, Z = 4, F(000) = 904, μ = 1.084 mm-1, R = 0.0440, GOF = 0.849 (crystal 2). The structures were solved by direct methods and refined by least-squares techniques to a final agreement factor of 0.0370 based on 1505 observed reflections and 0.0440 on 1477 observed reflections with I ≥ 2σ(I) for crystal 1 and crystal 2, respecially. There are different arrangements between the crystals 1 and 2, while the two crystals have same formula and similar molecular configuration. The nickel atom in the two crystals has a square-planar configuration formed by N2O2 donor atoms from the planar hydrazone ligand.
