| Popis: | A one-dimensional ladder-type coordination polymer, poly[[(μ2-hydroxido)(μ2-1H-pyrazole-3,5-dicarboxylato)gallium(III)] monohydrate], [Ga(C5H2N2O4)(OH)(H2O)]n or [Ga(HPDC)(OH)(H2O)]n, I, isotypic with a V3+ coordination polymer previously reported by Chen et al. [J. Coord. Chem. (2008). 61, 3556–3567] was prepared from Ga3+ and pyrazole-3,5-dicarboxylic acid monohydrate (H3PDC·H2O). Compound I was isolated using three distinct experimental methods: hydrothermal (HT), microwave-assisted (MWAS) and one-pot (OP) and the crystallite size should be fine-tuned according to the method employed. The coordination polymeric structure is based on a dimeric Ga3+ moiety comprising two μ2-bridging hydroxide groups, which are interconnected by HPDC2− anionic organic linkers. The close packing of individual polymers is strongly directed by the supramolecular interactions, namely several O—H...O and N—H...O hydrogen-bonding interactions. |
