abstract A one-dimensional ladder-type coordination polymer, poly[[(mu(2)-hydroxido)(mu(2)-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 center dot 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 mu(2) -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 center dot center dot center dot O and N-H center dot center dot center dot O hydrogen-bonding interactions.
