Popis:	Single crystals of the title compound, A, have been prepared and studied structurally by X-ray analysis. A crystallizes in the space group P21/n with Z = 4 and lattice parameters a = 11.174(3), b= 15.627(5), c= 8.148(3) Å and β = 92.82(3)°. Within the limits of error the π-bonded cyclobutadiene ring is a square with an average C-C-bond distance of 1.465 Å ; the methyl groups are displaced away from the nickel atom, the average distance between the ring plane and the methyl C-atoms being 0.15 Å. The sulfur containing five membered ring has a cyclic delocalized electron distribution.
