The polytypism of crystals of the mixed compound Cu(L-Ala)(L-Ser)

Abstract

Atomic structures of two polytypic modifications of crystals of mixed copper(II) compound Cu(L-Ala)(L-Ser) with optically active α-alanine (Ala) and serine (Ser) were studied by the electron diffraction analysis method: I - a=9.20(2) Å, b=9.61(1) Å, c=5.09(1) Å, γ=92.6(3)°, Z=2, space group of symmetry P21; II - a=18.40(2) Å, b=9.61(1) Å, c=5.09(1) Å, γ=92.6(3)°, Z=4, space group of symmetry C21.
