| The crystal structure of the title compound, [Zn2(C 8H7O2)4(H2O) 2]·[Zn2(C8H7O 2)4(C6H6N2O) 2]·2H2O, consists of two kinds of dinuclear Zn II complexes (complex A and complex B) and uncoordinated water molecules. In complex A, [Zn2(C8H7O 2)4(H2O)2], each Zn cation is chelated by a 4-methyl-benzoate (PMB) anion and coordinated by a water molecule, and is further bridged by two PMB anions in a trigonal-bipyramidal geometry. In complex B, [Zn2(C8H7O2) 4(C6H6N2O)2], each ZnII cation is coordinated by a monodentate PMB anion and one nicotinamide (NA) ligand, and is further bridged by two PMB anions in a tetra-hedral geometry. Weak intra-molecular π-π stacking between adjacent benzene rings is observed in complex B, the centroid-centroid distance being 3.710 (2) Å. Extensive O-H⋯O and N-H⋯O hydrogen bonding and weak C-H⋯O hydrogen bonding is present in the crystal structure. The crystal studied was a racemic twin; the minor twin component refined to 38%. |
