“…The maximum deviation from the least squares plane through the atoms Pd, N1, N2, O1 and O5 is 0.026 Å for N2. The distances Pd-O (1.976 (8), 2.024 (7) Å) and Pd -N (2.005 (11), 2.072 (9) Å) are in agreement with the values observed for other Pd(II) amino acid derivatives, like cisbis(L-tyrosinato)-palladium(II) hemihydrate (Jarzab et al, 1973), bis(L-tyrosinato)-palladium(II) (Sabat et al, 1979), bis-(L-valinato)-palladium(II) monohydrate (Pletnev et al, 1992); Hao et al, 2007), cis-bis(L-aspartato-N,O)-palladium(II) (Gao et al, 2008) or bis(L-serinato)-palladium(II) (Vagg, 1979). For both the hydrogen glutatmate ligands, the five membered PdNC 2 O chelate rings adopt envelope conformations with a nearly coplanar arrangement of the Pd, O, C and N atoms at the flap positions.…”
