In the title Er(III)-erythritol complex, [Er(NO3)3(C2H5OH)(C4H10O4)], the Er(III) cation is chelated by one erythritol mol-ecule, three nitrate anions and an ethanol mol-ecule, completing an irregular ErO10 coordination geometry. The Er-O bond lengths are in the range 2.348 (3)-2.583 (3) Å. In the crystal, extensive O-H⋯O hydrogen bonding links the mol-ecules into a three-dimensional supra-mole...

The hydro-thermal reaction of SrCO(3) and 2-bromo-benzoic acid in CH(3)OH-H(2)O afforded the Sr(II) title polymeric complex, [Sr(C(7)H(4)BrO(2))(2)(H(2)O)(2)](n). Within the coordination sphere, the Sr(II) ion is located on a crystallographic twofold axis, and is coordinated by eight O atoms from two water mol-ecules and four carboxyl-ate groups of 2-bromo-benzoate ligands in an irregular coord...

In the mixed ligand title compound, [Cd(C(6)H(11)NO(2))(C(7)H(4)NO(4))(2)(H(2)O)], which exhibits a discrete mononuclear structure, the Cd(II )atom is in a distorted octa-hedral geometry, surrounded by five carboxyl-ate O atoms and one coordinated water mol-ecule. The piperdinium ring adopts a chair conformation and the two 4-nitro-benzoate rings are oriented at a dihedral angle of 75.8 (1)°. I...

In the title coordination polymer, [Cd(C(16)H(12)O(8)S)(H(2)O)(2)](n), the Cd(II) ion is situated on a crystallographic twofold rotation axis, being coordinated by four O atoms from two bidentate 4,4'-[sulfonyl-bis-(1,4-phenyl-ene-oxy)]diacetate (L) ligands and two water mol-ecules in a highly distorted CdO(6) octa-hedral geometry. Each complete ligand L, which is also generated by twofold symm...
