metal-organic compounds
The title compound consists of discrete centrosymmetric [Ni(C10H12N3O2)2] molecules. The coordination around the Ni atom is square planar, involving four oxime N atoms of two chelating C2H2N2O2 groups. The oxime O atoms are linked by an intramolecular hydrogen bond [O
O = 2.546 (2) Å]. The Ni—N distances are 1.891 (2) and 1.846 (2) Å and the N—Ni—N angle within the NiC2N2 chelate ring is 82.75 (8). In the central portion of the molecule, the C=N distances are equal [1.297 (3) and 1.298 (3) Å] while the two N—O distances are different [1.303 (3) and 1.386 (3) Å].
