چکیده
In the title compound, [Mg(C6H2N2O4)(H2O)4]·H2O, the Mg(II) ion is coordinated by a fully deprotonated pyrimidine-4,6-dicarboxyl-ate mol-ecule, via a ring N and a carboxyl-ate O atom, and by four water O atoms at the apices of a slightly distorted octa-hedron. In the crystal, mol-ecules are linked by O-H⋯O and O-H⋯N hydrogen bonds, forming a three-dimensional network.

The two independent Mn(II) ions in the polymeric title compound, {[Mn(2)(C(6)H(2)N(2)O(4))(C(10)H(8)N(2))(H(2)O)(6)]SO(4)·3H(2)O}, exhibit distorted MnN(2)O(4) octa-hedral coordination geometries, with the pyrimidine-4,6-dicarboxyl-ate (pmdc) ligand acting in the bis-chelating μ-(κO,κN:κO',κN') bridging mode and the 4,4'-bipyridine (bpy) ligand in the μ-(κN:κN') bridging mode. The remaining coo...

The title structure, {[Ba(0.71)Sr(1.29)(C(4)HO(4))(4)(H(2)O)(10)]·H(2)O}(n), is built from dimers of edge-sharing monocapped square anti-prisms [(Ba/Sr)O(3)(H(2)O)(6)], in which barium and strontium are statistically disordered [ratio 0.353 (8):0.647 (8)] on the same crystallographic site. Such dimers are connected via bidentate hydrogen squarate groups [HC(4)O(4)](-), leading to chains that pr...
