Potassium (4-carboxypyridine-2,6-dicarboxylato)dioxidovanadate(V) monohydrate

A. A. Holder and D. VanDerveer

Abstract: 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.
