Abstract:

The two allomers of the title complex of [pentanetrione 2, 4-bis(salicylhydrazonato)] nickel (II), Ni1C19H16N4O5, crystallize in the monoclinic system, and space group C2/c, a=1.03076(9)nm, b=1.9105(1) run, c=0.93305(8)nm, beta=101.490(4)degrees, V=1.8006(3)nm(3), D-c=1.620g (.) cm(-3), Z=4, F(000) =904, mu= 1. 119mm(-1), R=0.0370,GOF=0.748(crystal 1); a=2. 1949(3)nm, b=0.9901(2)nm, c=0.8568(1)nm, beta= 92. 799 (6) degrees, V = 1. 8597 (5) nm(3), D. = 1. 568g (.) cm(-3), Z = 4, F(000) = 904, A = 1. 084min (-1), R = 0. 04401 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 greater than or equal to 2 sigma ( 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.
