[Ni (C~ 3H~ 4N4)], Mr= 284.98, monoclinic, P2Jc, a= 10.096 (2), b= 9-360 (2), c= 30.565 (4) A, fl= 119.45 (2), V= 2515-1 (9) A3, Z= 8, Ox= 1.505 g cm-3, Cu Ka,, t= 1.5418/~,/z= 20.22 cm-1, F (000)= 1168, T= 298 (2) K, 437 parameters refined, final R= 0.038 for all 2587 reflections. The complex takes a square-planar geometry around the Ni atom. Although the coordination geometries of the two crystallographically independent complexes are quite similar to each other, significant differences in planarity and Ni--N distances are observed.Introduction.
