Bis(l-serinium) oxalate dihydrate: polymorph II.

ABSTRACT: A corrected and improved structure of the polymorph II of 2C3H8NO3 (+)·C2O4 (2-)·2H2O, based on single-crystal data, is presented. The structure is refined with anisotropic displacement parameters for all non-H atoms and all H atoms are located. Due to the charged moieties, the structure is classified as a mol-ecular salt. Inter-molecular O-H?O(-), O-H?O and N(+)-H?O(-)hydrogen bonds link the components of the structure. The l-serinium cations and oxalate anions form a network of channels in [100] direction, filled with the water molecules of crystallization. The dihedral angle between the CO2 units of the oxalate dianion is 10.2?(3)°

A new polymorph of magnesium oxalate dihydrate.

Project description:In the asymmetric unit of the title compound, catena-poly[[diaqua-magnesium(II)]-?-oxalato], [Mg(C(2)O(4))(H(2)O)(2)](n), there is one Mg atom in an octa-hedral coordination with site symmetry 222, a unique C atom of the oxalate anion lying on a twofold axis, an O atom of the anion in a general position and a water O atom at a site with imposed twofold rotation symmetry. The Mg(2+) ions are ligated by water mol-ecules and bridged by the anions to form chains that are held together by O-H?O hydrogen bonds. The structure of the title compound has already been reported in a different space group [Lagier, Pezerat & Dubernat (1969 ?). Rev. Chim. Miner.6, 1081-1093; Levy, Perrotey & Visser (1971 ?). Bull. Soc. Chim. Fr. pp. 757-761].

Bis(tetra-ethyl-ammonium) oxalate dihydrate.

Project description:The title compound, 2C(8)H(20)N(+)·C(2)O(4) (2-)·2H(2)O, synthesized by neutralizing H(2)C(2)O(4)·2H(2)O with (C(2)H(5))(4)NOH in a 1:2 molar ratio, is a deliquescent solid. The oxalate ion is nonplanar, with a dihedral angle between carboxyl-ate groups of 64.37?(2)°. O-H?O hydrogen bonds of moderate strength link the O atoms of the water mol-ecules and the oxalate ions into rings parallel to the c axis. The rings exhibit the graph-set motif R(4) (4)(12). In addition, there are weak C-H?O inter-actions in the crystal structure.

A polymorph structure of copper(II) hydrogenphosphite dihydrate.

Project description:The title compound, poly[[diaqua-copper(II)]-μ(3)-hydrogenphosphito], [Cu(HPO(3))(H(2)O)(2)](n), (I), has been prepared by hydro-thermal synthesis at 393 K. Its non-centrosymmetric polymorph structure, (II), was known previously and has been redetermined at 193 (2) K [El Bali & Massa (2002 ▶). Acta Cryst. E58, i29-i31]. The Cu atoms in (I) and (II) are square-pyramidal coordinated. A distorted octa-hedral geometry around the Cu atoms is considered by including the strongly elongated apical distances of 2.8716 (15) Å in (I) and 3.000 (1) Å in (II). The Cu⋯Cu separation of the dimeric unit is 3.1074 (3) Å. The secondary building units (SBU) (the Cu(2)O(2) dimer and two HPO(3) units) in (I) are inversion related and form a two-dimensional layered structure, with sheets parallel to the bc plane, whereas in the structure of (II), the chain elements are connected via screw-axis symmetry to form a three-dimensional microporous framework. In both polymorph structures, strong O-H⋯O hydrogen bonds are observed.

(Diethyl-enetriamine)bis-(theophyllinato)zinc(II) dihydrate.

Project description:In the title compound, [Zn(C(7)H(7)N(4)O(2))(2)(C(4)H(13)N(3))]·2H(2)O, the Zn(II) ion is penta-coordinated by three N atoms of the diethyl-enetriamine ligand and one N atom of each of the two theophyllinate anions in a distorted trigonal-bipyramidal geometry. The Zn-N distances range from 2.076 (3) to 2.221 (3) Å. The crystal packing is stabilized by O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds involving the theophylline and diethyl-enetriamine ligands and uncoordinated water mol-ecules.

Bis(isonicotinamide-?N)bis-(4-methyl-benzoato-?O)copper(II) dihydrate.

Project description:In the centrosymmetric title compound, [Cu(C(8)H(7)O(2))(2)(C(6)H(6)N(2)O)(2)]·2H(2)O, the Cu(II) ion is located on a crystallographic inversion center. The asymmetric unit is completed by one 4-methyl-benzoate anion, one isonicotinamide (INA) ligand and one uncoordinated water mol-ecule; all the ligands are monodentate. The two O and the two N atoms around the Cu(II) ion form a slightly distorted square-planar arrangement. The dihedral angle between the carboxyl-ate group and the attached benzene ring is 13.86?(9)°, while the pyridine and benzene rings are oriented at a dihedral angle of 86.08?(5)°. The uncoordinated water mol-ecules are linked to the INA ligands by O-H?O hydrogen bonds. In the crystal structure, inter-molecular O-H?O, N-H?O and C-H?O hydrogen bonds link the mol-ecules into a three-dimensional network.

Tetra-aqua-bis-(piperazin-1-ium)cobalt(II) bis-(sulfate) dihydrate.

Project description:In the centrosymmetric title compound, [Co(C4H11N2)2(H2O)4](SO4)2·2H2O, the Co(II) atom is coordinated in a distorted octa-hedral geometry by four water O atoms and two piperazinium N atoms. These four water O atoms define an equatorial plane with a maximum deviation of 0.0384 (1) Å while the two piperazinium N atoms complete the octa-hedron in the axial positions. Neighboring complex mol-ecules and sulfate anions are connected through an extensive network of N-H⋯O and O-H⋯O hydrogen bonds, which link the different chemical species into layers in the ab plane. Additional Owater-H⋯O hydrogen bonds involving the non-coordinating water mol-ecules and C-H⋯O inter-actions connect these layers into a three-dimensional supra-molecular structure.

Tetra-aqua-bis(orotato-?O)cobalt(II) dihydrate.

Project description:In the title Co(II) complex, [Co(C(5)H(3)N(2)O(4))(2)(H(2)O)(4)]·2H(2)O, the Co(II) ion is located on an inversion center and is coordinated by two orotate (2,6-dioxo-1,2,3,6-tetrahydropyrimidine-4-carboxylate) anions and four water mol-ecules in a slightly distorted octa-hedral geometry. The dihedral angle between the carboxyl-ate group and the attached orotate ring is 1.2?(3)°. In the crystal structure, inter-molecular O-H?O, N-H?O and C-H?O hydrogen bonds link the mol-ecules into a three-dimensional network. ?-? contacts between the orotate rings [centroid-centroid distances = 3.439?(2) and 3.438?(2)?Å] further stabilize the structure.

Tris(ethylenediamine)cobalt(II) bis(tetra-hydroxypentaborate) dihydrate.

Project description:The novel pentaborate with a transition-metal complex as counter-cation and with water of crystallization, tris(ethylenediamine)cobalt(II) bis[4,4',6,6'-tetrahydroxy-2,2'-spirobi(cyclotriboroxane)(1-)] dihydrate, [Co(C(2)H(8)N(2))(3)][B(5)O(6)(OH)(4)](2)·2H(2)O, forms a three-dimensional supra-molecular framework through O-H?O hydrogen bonding among the [B(5)O(6)(OH)(4)](-) anions with large channels along the a axis in which the templating [Co(en)(3)](2+) cations (en = ethylenediamine) and water mol-ecules are located. The crystal packing is consolidated by additional O-H?O and N-H?O hydrogen bonds.

Bis(2,2'-bipyridyl dioxide-?N,N')bis-(tricyano-methanido)cobalt(II) dihydrate.

Project description:In the title compound, [Co(C(4)N(3))(2)(C(10)H(8)N(2)O(2))]·2H(2)O, a novel tricyano-methanide complex, the Co(II) atom is located on an inversion center and has a distorted octa-hedral coordination with two 2,2'-bipyridyl dioxide (dpdo) mol-ecules and two trans tricyano-methanide (tcm) anions. The equatorial plane is formed by the four O atoms of the two chelating dpdo ligands, with one N atom of each of the two tcm ligands occupying an apical position. There is a disordered solvent water mol-ecule in the asymmetric unit (occupancy ratio 0.63:0.37). These water mol-ecules result in the formation of O-H?O and O-H?N hydrogen bonds, building a layer parallel to (100). The layers are linked by C-H?N hydrogen-bonding inter-actions, leading to a three-dimensional network.
