Crystal structure of hexa-aqua-dichlorido-ytterbium(III) chloride.

ABSTRACT: The crystal structure of the title compound, [YbCl2(H2O)6]Cl, was determined at 110 K. Samples were obtained from evaporated aceto-nitrile solutions containing the title compound, which consists of a [YbCl2(H2O)6](+) cation and a Cl(-) anion. The cations in the title compound sit on a twofold axis and form O-H⋯Cl hydrogen bonds with the nearby Cl(-) anion. The coordination geometry around the metal centre forms a distorted square anti-prism. The ytterbium complex is isotypic with the europium complex [Tambrornino et al. (2014 ▶). Acta Cryst. E70, i27].

Aqua-bis-(1,1,1,5,5,5-hexa-fluoro-acetyl-acetonato)[4'-(4-pyrid-yl)-2,2':6',2''-terpyridine]-ytterbium(III) chloride methanol monosolvate monohydrate.

Project description:The title compound, [Yb(C(5)HF(6)O(2))(2)(C(20)H(14)N(4))(H(2)O)]Cl·CH(3)OH·H(2)O, adopts an eight-coordinated geometry around the Yb(III) atom consisting of a 4'-(4-pyrid-yl)-2,2':6',2''-terpyridine (pytpy) ligand, two 1,1,1,5,5,5-hexa-fluoro-acetyl-acetonate (hfac) anions and an aqua ligand. In the solid state, the compound forms supra-molecular chains running along the b-axis via inter-molecular hydrogen bonds between the Yb-OH(2) unit and the N-atom donor of the 4-pyridyl pendant of pytpy, with an O⋯N distance of 2.686 (4) Å. A chloride counter-anion and lattice methanol and water solvent mol-ecules occupy a hydro-philic columnar space along the coordination chains. O-H⋯Cl hydrogen bonds occur. The two water molecules and the four trifluoromethyl groups are disordered over two sets of sites, each with different occupancy ratios.

Tris[4-(dimethyl-amino)-pyridinium][(bis-μ-dichlorido)-deca-aqua-dichlorido-dineodymium(III)] penta-chloride dihydrate.

Project description:The title compound, (C(7)H(11)N(2))(3)[Nd(2)Cl(4)(H(2)O)(10)]Cl(5)·2H(2)O, consists of three 4-(dimethyl-amino)-pyridinium cations, one of which is disordered about an inversion center, one [Nd(2)Cl(4)(H(2)O)(10)](2+) dication possessing inversion symmetry, five chloride anions, one of which is disordered over two inversion centers, and two lattice water mol-ecules. The 4-(dimethyl-amino)-pyridinium cations are protonated at the pyridine N atoms and form N-H⋯Cl hydrogen bonds with Cl(-) counter-ions. The dimethyl-amino groups (C/N/C) lie close to the plane of the pyridinium rings, making dihedral angles of 1.6 (6)° and 6.5 (3)°. In the crystal, the [Nd(2)Cl(4)(H(2)O)(10)](2+) dications are linked via O-H⋯O and O-H⋯Cl hydrogen bonds, forming sheets lying parallel to the bc plane. These sheets are linked via O-H⋯Cl hydrogen bonds, forming a three-dimensional network. The 4-(dimethyl-amino)-pyridinium cations are located in the cavities and linked to the framework by C-H⋯Cl interactions.

Crystal structure of cis-tetra-aqua-dichlorido-cobalt(II) sulfolane disolvate.

Project description:In the title compound, [CoCl2(H2O)4]·2C4H8SO2, the Co(II) cation is located on the twofold rotation axis and is coordinated by four water mol-ecules and two adjacent chloride ligands in a slightly distorted octa-hedral coordination environment. The cisoid angles are in the range 83.27 (5)-99.66 (2)°. The three transoid angles deviate significantly from the ideal linear angle. The crystal packing can be described as a linear arrangement of complex units along c formed by bifurcated O-H⋯Cl hydrogen bonds between two water mol-ecules from one complex unit towards one chloride ligand of the neighbouring complex. Two solvent mol-ecules per complex are attached to this infinite chain via O-H⋯O hydrogen bonds in which water mol-ecules act as the hydrogen-bond donor and sulfolane O atoms as the hydrogen-bond acceptor sites.

Crystal structure of poly[[hexa-aqua-tris-(μ-3,6-di-oxo-cyclo-hexa-1,4-diene-1,4-diolato)dierbium(III)] octa-deca-hydrate].

Project description:The title lanthanide complex, [Er2(C6H2O4)3(H2O)6]·18H2O, is isostructural with its La, Gd, Yb and Lu analogues. The Er3+ ion, located on a threefold rotation axis, is nine-coordinated in a distorted tricapped trigonal-prismatic geometry, which is completed by six oxygen atoms from three dhbq2- ligands and three oxygen atoms from coordinated water mol-ecules. Each dhbq2- ligand acts in a μ2-bis-(bidentate) bridging mode to connect two Er3+ ions to form honeycomb (6,3) two-dimensional sheets extending in the ab plane, having an Er⋯Er separation of 8.7261 (2) Å. In the crystal, extensive O-H⋯O hydrogen-bonding inter-actions involving the coordinated water mol-ecules and the water mol-ecules of crystallization, as well as the oxygen atoms of the dhbq2- ligands, generate an overall three-dimensional supra-molecular network.

Synthesis and structure determination of racemic (Δ/Λ)-tris-(ethyl-enedi-amine)-cobalt(III) trichloride hemi(hexa-aqua-sodium chloride).

Project description:The synthesis and crystal structure of the title racemic compound, [Co(C2H8N2)3]Cl3.{[Na(H2O)6]Cl}0.5, are reported. The trivalent cobalt atom, which resides on a crystallographic threefold axis, is chelated by a single ethyl-ene di-amine (en) ligand and yields the tris-chelate [Co(en)3]3+ cation with distorted octa-hedral geometry after the application of crystal symmetry. The sodium cation (site symmetry ), has a single water mol-ecule bound to it in the asymmetric unit and yields a distorted, octa-hedrally coordinated hydrated [Na(H2O)6]+ cation after the application of symmetry. One of the chloride ions lies on a general position and the other has site symmetry. An extensive array of C-H⋯O, N-H⋯Cl and O-H⋯Cl hydrogen bonds exists between the ethyl-ene di-amine ligands, the water mol-ecules of hydration, and the anions present, thereby furnishing solid-state stability.

Crystal structure of bis-(μ<sub>2</sub>-5-nona-noylquinolin-8-olato)bis-[aqua-dichlorido-indium(III)].

Project description:Crystallization of 5-nona-noyl-8-hy-droxy-quinoline in the presence of InCl3 in aceto-nitrile yields a dinuclear InIII complex crystallizing in the space group P. In this complex, [In2(C18H22NO2)2Cl4(H2O)2], each indium ion is sixfold coordinated by two chloride ions, one water mol-ecule and two 8-quinolino-late ions. The crystal of the title complex is composed of two-dimensional supra-molecular aggregates, resulting from the linkage of the Owater-H⋯O=C and Owater-H⋯Cl hydrogen bonds as well as bifurcated Carene-H⋯Cl contacts.

Crystal structure of bis-(di-methyl-ammonium) hexa-aqua-nickel(II) bis-(sulfate) dihydrate.

Project description:In the title salt, (C2H8N)2[Ni(H2O)6)](SO4)2·2H2O, the Ni(II) cation is located on a centre of inversion and exhibits a slightly distorted octa-hedral arrangement of water mol-ecules. The Ni-O bond lengths in the complex [Ni(H2O)6](2+) cation show a distribution as in the related Tutton salt (NH4)2[Ni(H2O)6](SO4)2, but are longer in average [2.056 (13) versus 2.037 (12) Å]. The noncoordinating water mol-ecules and di-methyl-ammonium cations connect the sulfate and [Ni(H2O)6](2+) octa-hedra via O-H⋯O and N-H⋯O hydrogen bonds from weak up to medium strength into a three-dimensional framework whereby the complex metal cations and sulfate anions are arranged in sheets parallel (001).

Crystal structure of bis-(di-methyl-ammonium) hexa-aqua-cobalt(II) bis-(sulfate) dihydrate.

Project description:The title salt, (C2H8N)2[Co(H2O)6)](SO4)2·2H2O, is isotypic with (C2H8N)2[Ni(H2O)6)](SO4)2·2H2O. The Co-O bond lengths in the [Co(H2O)6](2+) complex cation show very similar distances as in the related Tutton salt (NH4)2[Co(H2O)6)](SO4)2 [average 2.093 (17) Å], but are significantly longer than in the isotypic Ni(II) compound (Δd ≃ 0.04 Å). The cobalt cation reaches an overall bond-valence sum of 1.97 valence units. The S-O distances are nearly equal, ranging from 1.454 (4) to 1.470 (3) Å [mean 1.465 (12) Å]; however, the O-S-O angles vary clearly from 108.1 (2) to 110.2 (2)° [average bond angle 109.5 (9)°]. The non-coordinating water mol-ecules and di-methyl-ammonium cations connect the sulfate tetrahedra and the [Co(H2O)6](2+) octa-hedron via O-H⋯O and N-H⋯O hydrogen bonds of weak up to medium strength into a three-dimensional framework whereby the complex metal cations and sulfate anions are arranged in sheets parallel to (001).

Poly[hexa-aqua-tri-μ-malonato-didysprosium(III)].

Project description:The title compound, [Dy(2)(C(3)H(2)O(4))(3)(H(2)O)(6)](n), forms a coordination polymeric structure comprising hydrated dysprosium ions and malonate ligands. In the asymmetric unit, there are one dysprosium ion, one and a half malonate ligands, and three water mol-ecules. Each Dy(III) atom is coordinated by six O atoms from four malonate ligands and by three water mol-ecules, and displays a tricapped trigonal-prismatic coordination geometry. The malonate ligands adopt two types of coordination mode, linking dysprosium centres to form a three-dimensional coordination polymer. The extensive network of hydrogen bonds in this polymer enhances the structural stability.

Bis[hexa-amminecobalt(III)] penta-chloride nitrate.

Project description:The title compound, [Co(NH(3))(6)](2)Cl(5)(NO(3)), was obtained under hydro-thermal conditions. The asymmetric unit contains three Co(3+) ions, one lying on an inversion center and the other two located at 2/m positions. All Co(3+) ions are six-coordinated by NH(3) mol-ecules, forming [Co(NH(3))(6)](3+) octahedra, with Co-N distances in the range 1.945 (4)-1.967 (3) Å. The nitrate N atom and one of the O atoms lie at a mirror plane. Among the Cl(-) anions, one lies in a general position, one on a twofold axis and two on a mirror plane. N-H⋯O and N-H⋯Cl hydrogen bonds link the cations and anions into a three-dimensional network.
