Abstract:
The self-assembly of the title dinuclear complex, namely (mu-p-phenylenediamine-N,N,N',N'-tetraacetato)bis[aqua(1,10-phenanthroline)nickel(II)] dodecahydrate, [Ni(2)(C(14)H(12)N(2)O(8))(C(12)H(8)N(2))(2)(H(2)O)(2)].12H(2)O, through intricate noncovalent interactions 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 molecules form one-dimensional chains in which cyclic water tetramers act as two types of building blocks. The water molecules play a significant role in the stabilization of the three-dimensional supramolecular framework. Intramolecular ;aryl-metal chelate ring' pi-pi interactions are also observed.

Newman Projections
The organic molecules rotate across the single bonds leading to numerous temporary three-dimensional structures of varying energy known as conformers.

Phosphodiester Linkages
Phosphodiester bond forms when a phosphoric acid molecule (H3PO4) links with two hydroxyl groups (–OH) of two other molecules, forming two ester bonds. Two water molecules are released in this process. The phosphodiester bond is commonly found in nucleic acids (DNA and RNA) and plays a critical role in their structure and function.
Phosphodiester Bonds Link Nucleotides Together
DNA and RNA are polynucleotides or long chains of nucleotides that are linked together. A nucleotide is...
Conformations of Cyclohexane
The chair form is the most stable and derives its name from its resemblance to the “easy chair.” In the chair conformation, two carbon atoms are arranged out-of-plane — one above and one below, minimizing the torsional strain. In the chair form, the bond angle is very close to the ideal tetrahedral value,...
