(4-Carboxynaphthalene-1-carboxylato)bis[4-(1H-1,3,7,8-tetraazacyclopenta[l]phenanthren-2-yl)phenol]zinc(II) 4-carboxynaphthalene-1-carboxylate dihydrate

Abstract: In the title compound, [Zn(C₁₂H₇O₄)(C₁₉H₁₂N₄O)₂](C₁₂H₇O₄)·2H₂O or [Zn(L)₂(HNDC)](HNDC)·2H₂O, where HNDC is the naphthalene-1,4-dicarboxylate monoanion and L is 4-(1H-1,3,7,8-tetraazacyclopenta[l]phenanthren-2-yl)phenol, the Zn^II atom is five-coordinated by four N atoms from two L ligands, and one O atom from the HNDC monoanion in an approximate trigonal-bipyramidal geometry. Aromatic - stacking interactions between L ligands, and N-HO, O-HO and N-HO hydrogen bonds, stabilize the crystal structure.
