Abstract
The structure of primary nickel dithizonate Ni(Hdz)2 was determined from three-dimensional single-crystal X-ray data, collected by standard film techniques, and refined by the least-squares method to R= 0·12 for 2580 observed and unobserved reflections. The crystals are triclinic, space group P with a= 4·62, b= 10·99, c= 12·50 ± 0·02 A, α= 88·8, β= 97·4, γ= 99·1 ± 0·1°, and Z= 1. The molecule is centrosymmetric with the nickel atom in a square-planar environment bonded to each dithizone ligand through one nitrogen and one sulphur atom to give a five-membered chelate ring with Ni–S 2·19 and Ni–N 1·87 A. The unique non-phenyl hydrogen atom was located.
