ABSTRACT

The title complex, [PdCl2(C8H14N2O)2]·2H2O, was obtained by N–O bond cleavage of the oxa­diazo­line rings of the trans-[di­chlorido-bis­(2,5,5-trimethyl-5,6,7,7a-tetra­hydro­pyrrolo­[1,2-b][1,2,4]oxa­diazole-N1)]palladium(II) complex. The palladium(II) atom exhibits an almost square-planar coordination provided by two trans-arranged chloride anions and a nitro­gen 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 mol­ecules into double layers parallel to the bc plane.

Mentions: The slightly distorted square-planar coordination sphere around the PdII atom comprises two chloride anions and two nitro­gen atoms from two neutral organic ligands (Fig. 1 ▸). The Cl—Pd—Cl, N—Pd—N, and Cl—Pd—N angles all deviate by less that 5° from the ideal 90° or 180° angles. The Pd—N [mean value 2.0783 (16) Å] and Pd—Cl [mean value 2.336 (12) Å] bond lengths fall in the range of typical distances found in similar types of PdII complexes. The five-membered heterocyclic rings each have a twist conformation, with puckering parameters Q = 0.238 (4) Å, φ = −108.8 (8)° and Q = 0.245 (4) Å, φ = 69.9 (8)° for N1/C1–C4 and N3/C9–C12, respectively. The crystal structures of the 2-ethyl and 2-(4-bromo­phen­yl) analogues of the title compounds have been reported elsewhere (Lasri et al., 2009 ▸).
