The title complex, [Pr(2)(C(4)H(2)O(4))(3)(C(4)H(4)O(4))(H(2)O)(2)](n), was synthesized by reaction of praseodymium(III) nitrate hexa-hydrate with fumaric acid in a water-ethanol (4:1) solution. The asymmetric unit comprises a Pr(3+) cation, one and a half fumarate dianions (L(2-)), one half-mol-ecule of fumaric acid (H(2)L) and one coordinated water mol-ecule. The carboxyl-ate groups of the fu...

In the title coordination polymer, {[Sm(2)(C(4)H(2)O(4))(3)(H(2)O)(6)]·6H(2)O}(n), the Sm(III) ion is nine-coordinated by four O atoms from three different maleate ligands, two O atoms from one fumarate ligand and three O atoms from three water mol-ecules. The fumarate ligand lies on an inversion center. Adjacent Sm(III) ions are bridged by the maleate and fumarate ligands, forming a layer para...

In the title compound, [Fe(C(12)H(6)O(4))](n), the Fe(II) atom is coordinated by six O atoms from six symmetrically equivalent naphthalene-1,4-dicarboxyl-ate ligands in a strongly distorted octa-hedral geometry. These octa-hedra are connected via common edges into chains that elongate along the a axis, with Fe⋯Fe distances of 2.9712 (4) and 2.9724 (4) Å. The chains are linked via the naphthalen...
متن کامل1-[4-(Dimethylamino)benzylidene]-4-o-tolylthiosemicarbazide
The asymmetric unit of the title compound, C17H20N4S, contains two independent mol-ecules, the main difference between them being the dihedral angles between the benzene rings [19.99 (17) and 9.72 (17)°]. The mol-ecules both have a trans conformation about the C=N double bond and intra-molecular C-H⋯S and N-H⋯N hydrogen bonds are observed in both mol-ecules. In the crystal, mol-ecules are linke...
متن کاملBis(μ-cyclohexane-1,3-dicarboxylato)-κ3 O 1:O 4,O 4′;κ3 O 1,O 1′:O 4-bis[aqua(1,10-phenanthroline-κ2 N,N′)zinc(II)]
The cyclo-hexane-1,3-dicarboxyl-ate dianion in the dinuclear centrosymmetric title compound, [Zn(2)(C(8)H(10)O(4))(2)(C(12)H(8)N(2))(2)(H(2)O)(2)], has a chair conformation with both carboxyl-ate groups in equatorial positions. One carboxyl-ate group chelates a Zn(II) atom, whereas the other binds through one O atom only to confer a six-coordinate status to the N-heterocycle-chelated water-coor...
