A new dinuclear Zn^II compound with a 1,4-benzenedicarboxylate bridge

G.-B. Che

Abstract: In the compound ₂-1,4-benzenedicarboxylate-²O,O'-bis{aquachloro[4-(1H-1,3,7,8-tetraazacyclopenta[l]phenanthren-2-yl)phenol-²N,N']zinc(II)} dihydrate, [Zn₂Cl₂(1,4-BDC)(L)₂(H₂O)₂]·2H₂O, where 1,4-BDC is the 1,4-benzenedicarboxylate dianion, C₈H₄O₄^2-, and L is 4-(1H-1,3,7,8-tetraazacyclopenta[l]phenanthren-2-yl)phenol, C₁₉H₁₂N₄O, the Zn^II atom is five-coordinated by two N atoms from one L ligand, one Cl^- ion, an O atom from a 1,4-BDC anion and one water molecule in an approximate trigonal-bipyramidal geometry. The complete 1,4-BDC ligand is generated by inversion symmetry; it bridges two Zn^II atoms to form a dinuclear complex. Neighbouring complexes interact through - contacts and various kinds of hydrogen bonds, leading to a two-dimensional supramolecular structure.
