摘要

The whole mol#173;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#8242;-(pyridin-2-yl)methyl#173;idenebenzene-1,4-di#173;amine (PPMBD). The five-coordinated Hg2+ ions have a distorted square-pyramidal environment defined by two N atoms, viz. the imine and the other pyridyl Hg#8212;N = 2.467#8197;(6) and 2.310#8197;(6)#8197;#197;, respectively belonging to the bidentate imino#173;pyridine ligand, and three Cl atoms Hg#8212;Cl = 2.407#8197;(2), 2.447#8197;(2) and 3.031#8197;(2)#8197;#197;. The longest Hg#8212;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#8197;(4)#176;, while the planes of the pyridine ring and the terminal phenyl ring are oriented at a dihedral angle of 53.8#8197;(4)#176;. In the crystal, mol#173;ecules are linked by N#8212;H#8943;Cl and C#8212;H#8943;Cl hydrogen bonds, forming sheets parallel to (001).
