Abstract

The title complex, [PdCl₂(C₈H₁₄N₂O)₂]·2H₂O, was obtained by N-O bond cleavage of the oxa-diazo-line rings of the trans-[di-chlorido-bis-(2,5,5-trimethyl-5,6,7,7a-tetra-hydro-pyrrolo-[1,2-b][1,2,4]oxa-diazole-N¹)]palladium(II) complex. The palladium(II) atom exhibits an almost square-planar coordination provided by two trans-arranged chloride anions and a nitro-gen atom from each of the two neutral organic ligands. In the crystal, N-H⋯O, O-H⋯O and O-H⋯Cl hydrogen bonds link complex mol-ecules into double layers parallel to the bc plane.
