Solvothermal synthesis and characterisation of novel Gallium-sulphide compounds
… supertetrahedral gallium-sulphide compounds were synthesised under solvothermal conditions. Three-dimensional frameworks, which are analogous to previously reported structures, along with a large number of new hybrid supertetrahedral compounds were produced. Inorganic three-dimensional structures …

Hydrogen physisorptive storage in metal-organic frameworks (MOFs)
… with high crystallinity and good morphology was synthesised using either N,N-diethylformamide (DEF) or dimethylformamide (DMF) as solvent. As DMF is a cheaper solvent than DEF the synthesis conditions were optimised for the DMF-synthesised MOF-5 and detailed analyses performed. It was discovered …

Synthesis and Characterization of Crystalline Coordination Networks Constructed From Neutral Imidazole Containing Ligand and Rigid Aromatic Carboxylate
The work is focused on the investigation of synthesis and structure of crystalline coordination networks by combining first a row transition metal ion with one anionic and one neutral bridging ligand. In the field of crystalline coordination networks, the goal is to synthesize porous 3D crystalline …
