Novel trigonal-bipyramidal copper(II) complexes containing one discrete amino acid chelate: crystal structures of [Cu(L-val)(pmdt)]ClO4 and [Cu(aiba) (pmdt)]ClO4·H2O(L-val = L-valinate ion, aiba = α-aminoisobutyrate ion, and pmdt = N,N,N′,N″,N″-pentamethyldiethylenetriamine)
摘要:
The title mixed-ligand copper(II) complexes were characterized by X-ray crystallography. These complexes take on a trans (O-amino acid, N-central of pmdt) form, and their CuN4O core geometries are approximately regular trigonal bipyramidal, which is novel for copper(II) complexes containing a discrete amino acid chelate ring.
