Synthesis and crystal structure of cerium(IV) bis-(phosphite).

ABSTRACT: The structure of cerium(IV) bis-(phosphite), Ce(HPO₃)₂, has been solved by single-crystal X-ray diffraction and has trigonal (P-3m1) symmetry. The cerium(IV) cation exhibits site symmetry -3m. and is octa-hedrally coordinated by O atoms of the phosphite ligands (point group symmetry 3m.). The highly symmetrical compound has a layered structure parallel to the ab plane, and is closely related to zirconium(IV) bis-(phosphite) solved via powder X-ray diffraction with trigonal (P-3 symmetry. Structural details of the two compounds are comparatively discussed.

Synthesis, crystal structure and Hirshfeld surface of bis-(2-amino-pyridinium) hexa-chlorido-stannate(IV).

Project description:In the title mol-ecular salt, (C5H7N2)2[SnCl6], the cation is protonated at the pyridine N atom and the complete dianion is generated by a crystallographic centre of symmetry. In the crystal, N-H⋯Cl hydrogen bonds link the components into a three-dimensional network built up from the stacking of alternate cationic and anionic layers. The nature of the inter-molecular inter-actions has been analysed in terms of the Hirshfeld surfaces of the cations and the anions. The thermal behaviour and the Raman spectrum of the title compound are reported.

Crystal structure of bis-(cyclo-hexyl-ammonium) di-phenyl-dioxalatostannate(IV).

Project description:Reaction of oxalic acid and di-phenyl-tin dichloride in the presence of cyclo-hexyl-amine led to the formation of the title salt, (C6H14N)2[Sn(C6H5)2(C2O4)2]. The dianion is made up from an Sn(C6H5)2 moiety cis-coordinated by two chelating oxalate anions, leading to an overall distorted octa-hedral coordination geometry of the Sn(IV) atom. The negative charges are compensated by two surrounding cyclo-hexyl-ammonium cations adopting chair conformations each. In the crystal, anions and cations are linked via a network of N-H?O hydrogen bonds into a layered arrangement parallel to (101).

Crystal structure of bis-[4-(di-methyl-amino)-pyridinium] aqua-bis-(oxalato)oxidovanadate(IV) dihydrate.

Project description:The title organic-inorganic hybrid salt, (C7H11N2)2[V(C2O4)2O(H2O)]·2H2O, shows a distorted octa-hedral coordination environment for the vanadium(IV) atom in the anion (point group symmetry 2), with four O atoms from two symmetry-related chelating oxalate dianions and two O atoms in trans configuration from a coordinating water mol-ecule and a terminal vanadyl O atom. In the crystal, (001) layers of cations and anions alternate along [001]. The anionic layers are built up by inter-molecular O-H⋯O hydrogen bonds involving the coordinating and solvent water mol-ecules. The cationic layers are linked to the anionic layers via N-H⋯O hydrogen bonds between the pyridinium group and the non-coordinating O atoms of the oxalate group. The 4-(di-methyl-amino)-pyridinium cations are also engaged in π-π stacking with their anti-parallel neighbours [centroid-to-centroid distance = 3.686 (2) Å]. Considering all supra-molecular features, a three-dimensional network structure is accomplished.

Synthesis, crystal structure and Hirshfeld surface analysis of bis-(caffeinium) hexa-chlorido-platinum(IV) in comparison with some related compounds.

Project description:The mol-ecular and crystal structure of the title compound, (C8H11N4O2)2[PtCl6], synthesized from hexa-chloro-platinic acid and caffeine in methanol, was studied by single-crystal X-ray diffraction. The caffeinium cations form a double layer via hydrogen bonds and π-stacking inter-actions. The Hirshfeld surface analysis showed that the largest contribution to the crystal packing is made by H⋯H (31.2%), H⋯Cl/Cl⋯H (22.6%), O⋯H/H⋯O (21.9%) contacts for the cation and H⋯Cl/Cl⋯H (79.3%) contacts for the anion.

Crystal structure of hepta-guanidinium nona-hydrogen bis-[α-hexa-molybdoplatinate(IV)] hepta-hydrate.

Project description:The title compound, (CH6N3)7H9[PtMo6O24]2·7H2O, containing the well-known Anderson-type heteropolyoxomolybdate, was obtained by recrystallization of its powdered guanidinium salt. The protonated O atoms in the polyanion were confirmed by electron-density maps, inter-polyanion hydrogen bonds and bond-valance sums (BVS). The {[H4.5PtMo6O24]2}(7-) polyanion is the same as that already characterized in K7[H4.5PtMo6O24]2·11H2O [space group P-1; Lee & Joo (2010 ▶). Acta Cryst. E66, i8-i9]. The heteropolyanions form inversion-generated dimers, {[H4.5PtMo6O24]2}(7-), held together by each of the four μ3-O-H⋯μ1-O, two μ2-O-H⋯μ2-O hydrogen bonds and one centrosymmetric μ3-O-H-μ3-O hydrogen bond. The H atom of the centrosymmetric hydrogen bond is located on an inversion centre. One guanidinium ion and one water mol-ecule are equally disordered about a twofold rotation axis.

Crystal structure of bis-[cis-di-aqua-bis-(phen-an-thro-line)cobalt(II)] bis-(citrato)germanate(IV) dinitrate.

Project description:The asymmetric unit of the title compound, [Co(C12H8N2)2(H2O)2]2[Ge(C6H5O7)2](NO3)2, features two complex [(C12H8N2)2(H2O)2Co]2+ cations, two NO3 - anions as well as one centrosymmetric [(C6H5O7)2Ge]2- anion. Two HCit ligands (Cit = citrate, C6H4O7) each coordinate via three different oxygen atoms (hy-droxy-late, α-carboxyl-ate, β-carboxyl-ate) to the Ge atom, forming a slightly distorted octa-hedron. The coordination polyhedron of the Co atom is also octa-hedral, formed by coordination of four nitro-gen atoms from two phenanthroline mol-ecules and two water oxygen atoms. In the crystal, the cations and anions are linked by hydrogen bonds and form layers parallel to the bc plane. The structure exhibits disorder of the NO3 - anion [disorder ratio 0.688 (9) to 0.312 (9)]. There are also highly disordered solvent mol-ecules (presumably water and/or ethanol) in the crystal structure; explicit refinement of these mol-ecules was not possible, and the content of the voids was instead taken into account using reverse Fourier transform methods [SQUEEZE procedure in PLATON; Spek (2015 ▸). Acta Cryst. C71, 9-18]. The given chemical formula and other crystal data do not take into account the unknown solvent mol-ecule(s).

Crystal structure of bis-(2-methyl-1H-imidazol-3-ium) μ-oxalato-bis-[n-butyl-tri-chlorido-stannate(IV)].

Project description:The Sn(IV) atom in the centrosymmetric anion of the title salt, (C4H7N2)2[Sn2(C4H9)2(C2O4)Cl6], is coordinated in a distorted octa-hedral mode by two O atoms of a bridging oxalate moiety, three Cl atoms and a C atom of an n-butyl group. The latter is disordered over two sets of sites in a 0.66:0.33 occupancy ratio. N-H⋯O and N-H⋯Cl hydrogen bonds involving the 2-methyl-imidazolium cation and neighbouring anions result in the formation of chains extending parallel to [001].

Crystal structure of bis-(9H-6-amino-purin-1-ium) hexa-fluorido-silicate(IV) dihydrate.

Project description:The asymmetric unit of the title compound, 2C5H6N5 (+)·SiF6 (2-)·2H2O, contains one adeninium cation, half of a hexa-fluorido-silicate anion located on an inversion centre and one lattice water mol-ecule. The adeninium cations are connected through N-H?N hydrogen bonds involving one H atom of the -NH2 group and the H atom of the protonated N atom of the adenine ring system, forming centrosymmetric ring motifs of the type R 2 (2)(10) and R 2 (2)(8), respectively. The overall connection of the cation leads to the formation of planar ribbons parallel to (122). In the ribbons, slipped ?-? stacking inter-actions, with a centroid-to-centroid distance of 3.6938?(9)?Å, an inter-planar distance of 3.455?Å and a slippage of 1.306?Å is observed. The hexa-fluorido-silicate anion and the water mol-ecule are linked through O-H?F hydrogen bonds [ring motif R 4 (4)(12)] into chains parallel to [100]. The cationic ribbons and anionic chains are finally connected through additional N-H?O, N-H?F and O-H?F hydrogen bonds into a three-dimensional network in which layers of adeninium cations and fluorido-silicate anions alternate parallel to (001).

Crystal structure of bis-[(5-oxo-oxolan-3-yl)triphen-ylphosphanium] hexa-iodido-tellurate(IV).

Project description:The asymmetric unit of the title salt, [C22H20O2P]2 (+)[TeI6](2-), consists of one triphenyl(5-oxooxolan-3-yl)phosphanium cation and one half of a hexa-iodido-tellurate(IV) dianion. The Te atom is located at an inversion centre and is octa-hedrally coordinated by six I atoms. The Te-I bond lengths range from 2.9255?(9) to 2.9439?(10)?Å. The I-Te-I angles between cis-iodide ligands are in the range 87.85?(3)-92.15?(3)°. In the crystal, the components are connected by C-H?I inter-actions. In the final refinement of the compound a void of 32?Å(3) was observed.
