چکیده
The asymmetric unit of the title compound, [NiCl(2)(C(19)H(9)F(6)N(3))], contains one half-mol-ecule residing on a crystallographic twofold rotation axis. The title compound crystallizes in space group C2/c while the previously reported polymorph was reported in P2(1)/c [Baldovino-Pantaleón et al. (2006 ▶). Adv. Synth. Catal.348, 236-242]. The Ni(2+) ion exhibits a penta-coordinate distorted trigonal-bipyramidal NiCl(2)N(3) geometry, with two Cl atoms in the equatorial plane. In the crystal, mol-ecules are linked by inter-molecular C-F⋯π [F⋯centroid = 2.9676 (14) Å] inter-actions.

The title complex, [Cu(C(13)H(10)ClN(2)O)(H(2)O)]NO(3)·H(2)O, was obtained by the reaction of 5-chloro-salicyl-aldehyde, 2-(amino-meth-yl)pyridine and copper nitrate in methanol. The first reported polymorph of this complex was triclinic [Liang et al. (2010 ▶). Acta Cryst. E66, m40]. The present polymorph crystallized in the monoclinic space group P2(1)/c. The Cu(II) ion is in a square planar e...
