Crystal structure Cu2(D-Ala)2(L-Ala)(L-Ser) and its structural peculiarities In comparison with mixed compound Cu2(D-Ala)(D-Ser)(L-Ser)2

Abstract

Atomic structures of mixed cooper (II) compounds Cu2(D-Ala)2(L-Ala)(L-Ser) and Cu2(D-Ala)(D-Ser)(L-Ser)2, containing in their composition the residues of alanine (Ala) and serine (Ser) in proportion 3:1 and 1:3, correspondingly, are interdependent and determined by the structure of the same initial structural fragment Cu(D-Ala)(L-Ser). Both compounds are related to polysomatic series, the structures of which are formed on the account of relative quantity variation and the sequence of alanine and serine distributing.
