Abstract

The hexamolybdocobaltate(III) pyridine-3-carboxylic acid (H3O)3[СОMО6O18(OH)6] .(С6H5NO2)2.5Н2О(compound 1) is an organic-inorganic hybrid material with a three-tilt crystal system belonged to space group P-1. This compound is a promising candidate for applications in the field of pharmaceutical chemistry and catalysis. Compound 1 was synthesized by the hydrothermal method. The prepared compound 1 was characterized by structural characteristics that were studied by methods: X-ray crystallography (XRC), NMR, and IR spectroscopies. The unit cell parameters of compound 1 were determined to be: a = 9.230 Å, b = 10.700 Å, с = 10.850 Å, α = 95.95о, β = 110.01°, γ = 105.11°, V = 949.9 Å3, and ρ = 2.479 g/cm3, Z = 1.
