Notes. X-Ray crystal structure of a copper(II) complex of the neurotoxic amino acid, DL-α-amino-β-methylaminopropionic acid

Abstract

The X-ray crystal structure of a copper(II) complex of the neurotoxic amino acid DL-α-amino-β-methyl-aminopropionic acid is reported [space group P2₁/a, a= 9.893(1), b= 11.192(5), c= 8.367(1)Å, β= 101.62(1)°]. The copper atom lies at a centre of symmetry with N₂O₂ planar co-ordination, Cu–O 1.942 and Cu–N 1.976 Å. The complex is weakly axially co-ordinated by perchlorate, Cu–O 2.547 Å.
