Rezumat | |
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.
