- Formation of a one-dimensional water chain containing two linking patterns of planar water tetra-mers
-
The self-assembly of the title dinuclear complex, namely (-p-phenyl-enediamine-N,N,N′,N′-tetra-acetato)bis-[aqua-(1, 10-phenanthroline)nickel(II)] dodecahydrate, [Ni2(C14H12N2O8)(C12H8N2)2(H2O)2] ·12H2O, through intricate noncovalent inter-actions results in a two-dimensional sheet-like structure. The dimer lies about an inversion centre at the centre of the p-phenylenediamine ring. Uncoordinated water mol-ecules form one-dimensional chains in which cyclic water tetra-mers act as two types of building blocks. The water mol-ecules play a significant role in the stabilization of the three-dimensional supra-molecular framework. Intra-molecular aryl-metal chelate ring π-π inter-actions are also observed.
