Single crystals of the title compound, [Gd(C 6 H 4 NO 2 ) 3 -(H 2 O) 2 ] n , were obtained by evaporation of an aqueous solution of isonicotinic acid and gadolinium(III) nitrate. The Gd III cation is eight-coordinated by four carboxylate O atoms of bridging isonicotinate anions, two carboxylate O at
