Conglomerate crystallization behavior of racemic [Co(N4)(aminoacidato)]2+ complexes
Crystal structures, absolute configurations, and crystalline packing features of nine complexes, namely, cis-α-Λ-(RR)(δλδ)-[Co(trien)(D-histidinato)](ClO4)2·2H2O 1, cis-β1-Δ-(RR)(λδδ)- [Co(trien)(L-asparaginato)](ClO4)22, cis-β2-Λ(SS)(λλδ)-[Co(trien)(L-valinato)](ClO4)2·H2O 3, cis-β2-Δ-(RR)(δδλ)[Co(trien)(D-methioninato)](ClO4)2 and its enantiomer 4, trans(N,t-N)-[Co(tren)(DL-leucinato)]X2, (X=ClO4−5, BF4−6, PF6−7), and trans(N,t-N)-[Co(tren)(DL- methioninato)]X2 (X=Br−8, Cl−(BF4−) 9) (trien=triethylenetetramine, tren=tris(2-aminoethyl)amine), have been determined. All compounds were prepared from racemic DL-amino acid. 1–3 crystallize as conglomerates. 5–7 are isomorphous and crystallize as the so-called conglomeratic solids. While 4, 8 and 9 undergo racemic crystallization. In 1–7, the carboxylic oxygen of the amino acid forms double hydrogen bonds with the amino hydrogen atoms of N4 and/or amino acidato of an adjacent cation. By these hydrogen bonds, cations having the same chirality are linked together into helical string. In the isomorphous 8 and 9, the cation containing L-methionine interacts with a cation containing D-methioninine, through hydrogen bonds, to form a racemic pair, and no spiral string arrangements are observed.
