Abstract

The crystal structure of the 4-methylpyridine adduct of bis[1-(2-thienyl)-4, 4,4-trifluoro-1,3-butanedionatolnickel(II) was determined by a three-dimensional x-ray analysis using counter data. The crystals are monoclinic,C2/c, witha = 9.330,b = 18.278,c = 17.855 Å, and β = 95.1°. The structure was refined by full-matrix least squares toR = 0.10. The molecule has a two-fold axis, and both enantiomers withcis configuration occur in the crystal. The solvation by 4-methylpyridine is shown to weaken the chelate bonds in the same way as doestrans hydration.
