Potassium (4-carboxypyridine-2,6-dicarboxylato)Dioxidovanadate(V) Monohydrate
Chemistry and Biochemistry
The title complex, K[V(C8H3NO6)O2]·H2O, was synthesized by reacting 4‐carboxypyridine‐2,6‐dicarboxylic acid (contaminated as a potassium salt) with NH4VO3 in aqueous solution. The title complex, with a vanadium(V) metal center, is a distorted square‐based pyramid. Its structure consists of chains of the anionic complexes in the direction of the b axis connected by potassium–oxygen interactions which range from 2.5981 (18) to 3.0909 (18) Å. These chains are linked to each other by hydrogen bonding between the O atoms of the complex and the water molecules.
