STABILIZING EFFECTS IN PD(II)-N-ARSO2-AMINO ACIDATE COMPLEXES - CRYSTAL AND MOLECULAR-STRUCTURE OF DISODIUM BIS(N-BENZENESULFONYLGLYCINATO-NO)PALLADATE(II) MONOHYDRATE

The crystal structure and 1H NMR study of Na2[Pd(BsglyNO)2]·H2O (BsglyNO=N-benzenesulfonylglycinate dianion) are reported. The crystals are monoclinic, space group P21/c with cell parameters: a=8.868(2), b=22.716(5), c=10.046(4) Å, β=98.07(3)°, Z=4. The structure consists of monomeric [Pd(BsglyNO)2]2− anions, sodium ions and lattice water molecules. The Pd atom shows a slightly distorted trans-coordination given by two independent BsglyNO dianions acting as bidentate ligands through one carboxylate oxygen and the deprotonated sulfonamide nitrogen. Intramolecular contacts of Pd with S, O and aromatic C atoms, and intramolecular stacking interactions involving phenyl rings are present. Some 1H NMR data in aqueous solution are also reported
