Bis{μ-2,5-bis[4-(2-pyridylmethylamino)phenyl]-1,3,4-oxadiazole}bis[dichloridomercury(II)]
In the title centrosymmetric compound, [Hg2Cl4(C26H22N6O)2], each HgII center adopts a distorted HgN3Cl2 trigonal bipyramidal coordination geometry, formed by two pyridine N atoms, one imine N atom and two chloride anions. Within the organic ligand, the oxadiazole ring is nearly coplanar with the tw...

| Summary: | In the title centrosymmetric compound, [Hg2Cl4(C26H22N6O)2], each HgII center adopts a distorted HgN3Cl2 trigonal bipyramidal coordination geometry, formed by two pyridine N atoms, one imine N atom and two chloride anions. Within the organic ligand, the oxadiazole ring is nearly coplanar with the two benzene rings [dihedral angles = 5.9 (4) and 6.5 (4)°] and nearly perpendicular to the two pyridine rings with the same dihedral angle of 77.4 (4)°. The two organic ligands bridge two HgII ions to form the macrocyclic complex. Intermolecular N—H...Cl and N—H...N hydrogen bonding helps to stabilize the crystal structure. |
