In this paper are reported structural and spectroscopic properties of (N-benzenesulphonylglycinato)triaquacopper (II) (complex I) and dipotassium bis (N-benzenesulphonylglycinato) cuprate (II) (complex II).The crystals of (I) are monoclinic, space group P2₁/c, Z = 4, with a = 12.736(4), b = 10.292(3), c = 10.402(3) Angstroem, β = 109.41(2) deg while those of complex (II) are orthorhombic, space group Pbca, with a = 23.333(8), b = 10.508(4), c = 16.989(5) Angstroem.In both complexes the aminoacid molecules act as bidentate via carboxylic oxygen and the amide nitrogen atom; in (I) three water molecules complete the coordination to tetragonal pyramidal, while in (II) coordination is square planar, tetrahedrally distorted involving two ligand molecules.The structure (I) was refined to a final R index of 0.0596 and (II) to R = 0.0466.
