    Notes: The title compound, bis{1-[(+)-(1R,3S)-1,2,2,3-tetramethylcyclopentyl]-3-[(-)-(1S,3R)- 1,2,2,3-tetramethylcyclopentyl]propane-1,3-dionato-O,O'}nickel(II), [Ni(C21H35O2)2], displays interesting stereochemical aspects due to the meso configuration of the 1,3-bis(1,2,2,3-tetramethylcyclopentyl)-1,3-propanedionate ligands. The Ni atom lies on an inversion center, with Ni—O distances of 1.842 (2) and 1.826 (2) Å.

    Notes: The enantiomer separation of 2-halocarboxylic acid esters on two chiral nickel(II) bis-((perfluoroacyl)terpeneketonates) by complexation gas chromatography is described. The quantitative entiomer separation of branched 2-halocarboxylic acid esters is achieved with nickel (II) bis (3-(heptafluorobutanoyl)(1R, 2S)-pinan-4-onate) 1 while unbranched 2-halocarboxylic acid esters are preferably separated on nickel(II) bis(3-(heptafluorobutanoyl)-(1S)-10-methylenecamphorate) 2. The metal chelates 1 and 2 are accessible in both enantiomeric forms allowing the determination of the enantiomeric excess (ee) effective and reliable.
