Comparative peculiarities of polytypy of crystals Cu(D-Ala)(L-Ser) and Cu2(D-Ala)(L-Ala)(D-Ser)(L-Ser)

Comparative peculiarities of polytypy of crystals Cu(D-Ala)(L-Ser) and Cu2(D-Ala)(L-Ala)(D-Ser)(L-Ser)

Atomic structures of two polytypic modifycations of crystals of mixed cooper (II) com- pound Cu(D-Ala)(L-Ser) with optically active α-alanine (Ala) and serine (Ser) were studied by the electron diffraction analysis method: modification I - a=9.26(2) Å, b=9.60(1) Å, c=4.98(1) Å, γ=91.2(3)°, Z=2,...
