Abstract

A pair of racemic (Delta Delta/Lambda) mu-[N,N ' -bis(2-aminoethyl)-1,2-ethanediamine-N1,N1 ' ,N2,N2 ']-bis[N,N '-(bis(2-aminoethyl)-1,2-ethanediamine-N, N ', N ", N ' ' ')]dinickel(II) compounds were prepared and structurally characterized by crystallography. The perchlorate salt (1) crystallizes in the space group Pbcn; while the 4,4 ' -biphenyldisulfonate (BPDS) salt (2) crystallizes in the chiral space group C2 with a pair of Delta Delta andLambda Lambda enantiomers in the unit cell, which represents the first example of kryptoracemic crystallization documented for a binuclear coordination compound. The extensive hydrogen bonds between the SO., groups of the BPDS anions and the amino hydrogens of the complex cations are accounted for the kryptoracemic crystallization pathway adopted by 2.
