Bis(guanidinium) tetra-iodidomercurate(II).

ABSTRACT: The Hg atom in the crystal structure of the title compound, (CH(6)N(3))(2)[HgI(4)], is tetra-hedrally coordinated by four I atoms. The [HgI(4)](2-) ions are inter-connected to the [C(NH(2))(3)](+) ions by N-H?I hydrogen bonds, forming a three-dimensional network. The four different observed Hg-I distances [2.760?(2), 2.7762?(15), 2.8098?(14) and 2.833?(2)?Å] are consistent with four different (127)I NQR frequencies observed, showing the existence of four unique I atoms in the tetra-iodidomercurate unit.

The Hg atom in the crystal structure of the title compound, (CH(6)N(3))(2)[HgI(4)], is tetra-hedrally coordinated by four I atoms. The [HgI(4)](2-) ions are inter-connected to the [C(NH(2))(3)](+) ions by N-H⋯I hydrogen bonds, forming a three-dimensional network. The four different observed Hg-I distances [2.760 (2), 2.7762 (15), 2.8098 (14) and 2.833 (2) Å] are consistent with four different (127)I NQR frequencies observed, showing the existence of four unique I atoms in the tetra-iodidomercura ...[more]

Bis(triphenyl-guanidinium) tetra-chlorido-cuprate(II).

Project description:The structure of the title compound, (C(19)H(18)N(3))(2)[CuCl(4)], consists of square-planar [CuCl(4)](2-) anions and triphenyl-guanidinium cations. The Cu(II) ion occupies a crystallographic inversion centre. In the cation, the dihedral angles between the phenyl rings and the plane defined by the central guanidinium fragment are in the range 51.9 (4)-64.4 (3)°. N-H⋯Cl hydrogen bonds assemble the ions into infinite chains running along the b axis.

Guanidinium tetra-bromidomercurate(II).

Project description:The Hg atoms in the crystal structure of the title compound, (CH(6)N(3))(2)[HgBr(4)], are tetra-hedrally coordinated by four Br atoms and the resulting [HgBr(4)](2-) tetra-hedral ions are linked to the [C(NH(2))(3)](+) ions by bromine-hydrogen bonds, forming a three-dimensional network. In the structure, the anions are located on special positions. The two different Hg?Br distances of 2.664?(1) and 2.559?(1)?Å observed in the tetra-bromidomercurate unit are due to the connection of Br atoms to different number of H atoms.

Crystal structure of bis-(N,N,N',N'-tetra-methyl-guanidinium) tetra-chlorido-cuprate(II).

Project description:In the structure of the title salt, (C5H14N3)2[CuCl4], the Cu(II) atom in the anion lies on a twofold rotation axis. The tetra-chlorido-cuprate(II) anion adopts a flattened tetra-hedral coordination environment and inter-acts electrostatically with the tetra-methyl-guanidinium cation. The crystal packing is additionally consolidated through N-H⋯Cl and C-H⋯Cl hydrogen bonds, resulting in a three-dimensional network structure.

Tetra-guanidinium bis-[citrato(3-)]cuprate(II) dihydrate.

Project description:The asymmetric unit of the title compound, (CH(6)N(3))(4)[Cu(C(6)H(5)O(7))(2)]·2H(2)O, contains one-half of a centrosymmetric Cu(II) complex anion, two guanidinium cations and a water mol-ecule. The Cu(II) ion, lying on a crystallographic inversion center, is hexa-coordinated with two citrate anions in a distorted octahedral geometry. An intra-molecular O-H?O hydrogen bond generates an S(6) ring motif. In the crystal structure, mol-ecules are linked into a three-dimensional framework by inter-molecular N-H?O and O-H?O hydrogen bonds.

μ-Pyrazine-bis-[tetra-aqua-cadmium(II)] μ-pyrazine-bis-[tetra-acetato-cadmium(II)].

Project description:In the title dinuclear ionic complex, [Cd(2)(C(4)H(4)N(2))(H(2)O)(8)][Cd(2)(CH(3)CO(2))(8)(C(4)H(4)N(2))], the cation and anion are disordered equally over a site with symmetry mmm. The Cd(II) ions and the N atoms of the bridging pyrazine ligand lie on the inter-section of two crystallographic mirror planes. The C atoms of the bridging pyrazine ligand lie on one of these mirror planes, and the acetate groups and water mol-ecules lie across the inter-secting mirror planes. Each Cd(II) atom in the cation is five-coordinated by four O atoms from four water mol-ecules and one N atom from the bridging pyrazine ligand, whereas each Cd(II) in the anion is nine-coordinated by four pairs of O atoms from the bidentate acetate ligands and one N atom from the bridging pyrazine ligand. In the crystal structure, each anion is surrounded by eight nearest-neighbour cations and vice versa. The crystal structure is stabilized by ionic inter-actions as well as by C-H⋯O inter-actions.

Bis(1,1-dimethyl-guanidinium) tetra-aqua-dimethyl-tin(IV) bis-(sulfate).

Project description:Single crystals of the title salt, (C(3)H(10)N(3))(2)[Sn(CH(3))(2)(H(2)O)(4)](SO(4))(2), formed concomitantly with the already known [Sn(CH(3))(3)](2)SO(4)·2H(2)O. In the title structure, the Sn(IV) atom displays a slightly distorted octa-hedral coordination geometry defined by four O water atoms in the equatorial positions and two methyl groups in the axial positions. In the crystal, various O-H?O and N-H?O hydrogen-bonding inter-actions between the organic cation and the coordinated water mol-ecules as donors and the sulfate O atoms as acceptors result in a three-dimensional structure. The Sn(IV) atom is located on an inversion centre, resulting in half of the complex metal cation being in the asymmetric unit.

Bis(tetra-phenyl-phospho-nium) tetra-chlorido-cobaltate(II).

Project description:The title compound, (C24H20P)2[CoCl4], was prepared under hydro-thermal conditions. In the crystal, the tetra-phenyl-phospho-nium cations are linked by pairs of weak C-H⋯π inter-actions into supra-molecular dimers; the Co(II) cations lie on twofold rotation axes and the tetra-hedral [CoCl4](2-) anions are linked with the tetra-phenyl-phospho-nium cations via weak C-H⋯Cl hydrogen bonds.

Bis(creatininium) tetra-chlorido-cadmate(II).

Project description:In the title compound, (C(4)H(8)N(3)O)(2)[CdCl(4)], the asymmetric unit comprises two creatininium cations and one tetra-chloridocadmate anion. Cd?O secondary bonding links one of the two imidazole rings and the anion into ion pairs. The free and bound cations form layers between which the [CdCl(4)](2-) anions are sandwiched. The Cd(II) atom adopts a distorted trigonal-bipyramidal geometry in which the Cd?O bond is axial. Inter-molecular N-H?Cl hydrogen bonds form a two-dimensional network parallel to (001) which ensures the junction between creatininium cations and [CdCl(4)](2-) anions.
