摘要：
The structures of catena-[K(μ6-Hba−O,O,O,O′,O′,O″)] (I) and catena-[Cs(μ6-Hba–O,O,O′,O′,O″,O″)] (II), where Н2ba is barbituric acid C4H4N2O3, were characterized by powder X-ray diffraction. Crystallographic data: a = 14.1603 (4) Å, b = 3.68977 (9) Å, c = 10.9508 (3) Å, β = 82.226 (1)°, V = 566.90 (3) Å3, space group P21/n, Z = 4 for I; a = 14.652 (1) Å, b = 11.7275 (7) Å, c = 3.8098 (3) Å, β = 79.140 (6)°, V = 642.90 (8) Å3, space group C2/m, Z = 4 for II. The structural topologies of alkali metal complexes with barbituric acid and some its derivatives were compared. The thermal stability of complexes I and II in an air atmosphere was studied.
