Crystal structure of di-?-chlorido-bis(chlorido-{N (1)-phenyl-N (4)-[(pyridin-2-yl-?N)methyl-idene]benzene-1,4-di-amine-?N (4)}mercury(II)).

ABSTRACT: The whole mol-ecule of the title complex, [Hg2Cl4(C18H15N3)2], is generated by inversion symmetry. It was synthesized from the pyridine-derived Schiff base N-phenyl-N'-[(pyridin-2-yl)methyl-idene]benzene-1,4-di-amine (PPMBD). The five-coordinated Hg(2+) ions have a distorted square-pyramidal environment defined by two N atoms, viz. the imine and the other pyridyl [Hg-N = 2.467?(6) and 2.310?(6)?Å, respectively] belonging to the bidentate imino-pyridine ligand, and three Cl atoms [Hg-Cl = 2.407?(2), 2.447?(2) and 3.031?(2)?Å]. The longest Hg-Cl bond is bridging about the inversion centre. In the ligand, the central ring and pyridine ring are oriented at a dihedral angle of 8.1?(4)°, while the planes of the pyridine ring and the terminal phenyl ring are oriented at a dihedral angle of 53.8?(4)°. In the crystal, mol-ecules are linked by N-H?Cl and C-H?Cl hydrogen bonds, forming sheets parallel to (001).
