چکیده
The crystal structure of the title compound, {[Ba(C4HO4)2(H2O)5]·H2O} n , consists of discrete double chains propagating along [010]. The chains are formed by Ba(II) ions linked by bridging hydrogen squarate ligands in a trans-bis-monodentate mode. In addition, the bridging hydrogen squarate ligands connect the chains into a ladder structure via a third coordinating O atom. The remaining coordination sites are occupied by five aqua ligands and a second mondendate hydrogen squarate ligand, forming a slightly distorted tricapped trigonal-prismatic geometry. O-H⋯O hydrogen bonds link the chains and solvent water mol-ecules into a three-dimensional network.

In the title coordination polymer, {[Ba(C(7)H(2)N(2)O(7))(H(2)O)(2)]·H(2)O}(n), the Ba(II) atom is ten-coordinated by seven O atoms from four 3,5-dinitro-salicylatate ligands, two μ(2)-bridging aqua ligands and one water mol-ecule. The coordination mode is best described as a bicapped square-anti-prismatic geometry. The 3,5-dinitrosalicylatate ligands bridge three Ba atoms. Centrosymmetrically ...

The structure of the title compound, [Sm(2)(C(4)O(4))(3)(H(2)O)(4)](n), consists of infinite-chain structural units, built from edge-sharing samarium SmO(7)(H(2)O)(2) polyhedra and linked via bis-monodendate squarate (sq1) groups. The chains extend along [100] in a zigzag mode and are interconnected by bis-chelating squarate (sq2) ligands into layers parallel to (101). Inter-layer hydrogen bond...

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...

In the title compound, {[Sr(C(7)H(4)FO(2))(2)(H(2)O)(2)]·H(2)O}(n), the Sr(II) atom is coordinated by six O atoms and one F atom from four 2-fluoro-benzoate ligands and two water mol-ecules, resulting in an irregular SrFO(8) coordination environment. The μ(3)-2-fluoro-benzoate ligand bridges three symmetry-related Sr(II) atoms, giving rise to a chain structure extending along [010]. The polymer...
