Abstract: The structure of the title compound, [Th(C₅H₃N₂O₂)₄(H₂O)₂]·3H₂O, contains monomeric molecules composed of a thorium(IV) ion coordinated by N,O-chelating groups donated by four pyrazine-2-carboxylate ligands [mean Th-N = 2.773 (30) Å and mean Th-O = 2.391 (17) Å] and two water O atoms [mean Th-O = 2.517 (30) Å]. The coordination polyhedron around the Th^IV ion is an irregular hexadecahedron.
