Sažetak

The crystal structures of bis(N-methyl-5-chlorosalicylideneiminato)
nickel(II) (A) and bis(N-ethyl-5-chlorosalicylideneiminato)
nickel(II) (B) have been determined by X-ray structure analysis
using heavy atom method and refined by fuU matrix leastsquares
procedure to R values of 0.044 and 0.040 for (A) and (B), respectively. Both structures have molecular centre of symmetry and the nickel atom in a planar coordination. Molecules of both complex compounds have »stepped« conformation with distinct difference in the step heights: 0.121 and 0.702 A in (A) and (B), respectively. The Ni-O and Ni-N bond lengths are 1.818 and 1.924 A in (A), and '1.830 and 1.916 A in (B).
