Diaquadioxobis(pyridine-3-carboxylato)uranium(VI)

The uranyl group in the title compound, [UO₂(C₆H₄NO₂)₂(H₂O)₂], with U-O 1.782 (4) Å, is sixfold coordinated by two water molecules [U-O 2.431 (4) Å] and two bidentate nicotinic acid anions (pyridine-3-carboxylato ions) [U-O 2.459 (4)-2.486 (4) Å]. Individual molecules are linked into chains by hydrogen bonds between coordinated water molecules and pyridine N atoms.
