Hydrogen Bonding System

Abstract The reaction of nitrophenols (picric acid, 2,6-dinitrophenol, and 2,4-dinitrophenol) with divalent metal oxinate (metal = Cu, Co, Ni, Mn, and Zn) produced a type of molecular complex, which comprises two molecules of the metal oxinate and one molecule of the nitrophenol. In the case of the Mg complex the ratio is 1:1. A definite charge-transfer band is detected for the Co(II) complex. A hydrogen bonding system O1...H+...O2 is suggested. This includes the proton of the nitrophenol and two oxygen atoms; each is related to a coordinated oxinate of two different metal oxinate molecules. Analytical and spectral evidence are in accordance with the tentatively suggested formulations.

Hydrogen Bonding System

The crystal structure of the title compound, C2H10N2 2+·C6H2O4S2−·2H2O, is built of ethylenediammonium dications, occupying a special position on an inversion center, thiophene-2,5-dicarboxylate dianions, in a special position on the twofold axis, and water molecules in general positions. All residues are involved in an extensive hydrogen-bonding system, which links them into a three-dimensional supramolecular arrangement.

Hydrated crystals of copper(II) colchiceine belong to the tetragonal space group P 432I2 with a 13·415(1), c 50·169(8) Å and Z 8. The structure has been refined to a conventional R factor of 0·077 for 4560 observed data. The tropolonic oxygens from two colchiceine molecules are coordinated to the copper atom in this bis-chelated complex to form a square planar arrangement. The sites of three of the waters are clearly defined, but the others are disordered over seven partially occupied sites. An intricate hydrogen-bonding system links the complex and water molecules into a three-dimensional network in the crystal.

The hydrogen bonding network in the crystals of the three saccharides was correlated with their gelling ability or inability, and unexpectedly, a 2D hydrogen-bonded system was found to show efficient gelation, whereas a 1D hydrogen bonding system was a nongelator.
