Guanidinium tetra-bromidomercurate(II).

ABSTRACT: 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.

Bis(guanidinium) tetra-iodidomercurate(II).

Project description: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.

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.

N,N,N',N'-Tetra-methyl-guanidinium tetra-phenyl-borate.

Project description:In the title salt, C5H14N3(+)·C24H20B(-), the C-N bond lengths in the central CN3 unit are 1.3322 (11), 1.3385 (12) and 1.3422 (12) Å, indicating partial double-bond character. The central C atom is bonded to the three N atoms in a nearly ideal trigonal-planar geometry [N-C-N angles = 119.51 (8), 119.81 (9) and 120.69 (8)°] and the positive charge is delocalized in the CN3 plane. The bond lengths between the N atoms and the terminal methyl groups all have values close to a typical single bond [1.4597 (12)-1.4695 (13) Å]. The crystal packing is caused by electrostatic inter-actions between cations and anions.

Crystal structure of tetra-guanidinium [hexa-hydrogen hexa-arsenato(V)tetra-vanadate(V)] tetra-hydrate.

Project description:The complete polyoxidometallate anion in the title compound, (CH6N3)4[H6V4As6O30]·4H2O, is generated by crystallographic inversion symmetry. The polyhedral building units are distorted VO6 octa-hedra and AsO3OH tetra-hedra. The VO6 units feature a short formal V=O double bond and are linked by a common edge. Two such V2O6 double octahedral units are linked by four isolated AsO3OH tetra-hedra to complete the anion, which features two inter-nal O-H⋯O hydrogen bonds. In the crystal, O-H⋯O hydrogen bonds between the polyoxidometallate anions generate (01-1) sheets. The sheets are connected by cation-to-cluster N-H⋯O hydrogen bonds, and cation-to-water N-H⋯O links also occur. The O atom of one of the water mol-ecules is disordered over two sites in a 0.703 (17):0.297 (17) ratio.

Project description:In the title complex, (CH(6)N(3))(2)[Zr(C(7)H(3)NO(4))(3)]·4H(2)O, the Zr(IV) ion lies on a twofold rotation axes and is coordinated by six O and three N atoms of three tridentate pyridine-2,6-dicarboxyl-ate ligands, forming a slightly distorted tricapped trigonal-prismatic geometry. In the crystal, O-H?O and N-H?O hydrogen bonds link the components into a three-dimensional network.

Guanidinium and Mixed Cesium-Guanidinium Tin(II) Bromides: Effects of Quantum Confinement and Out-of-Plane Octahedral Tilting.

Project description:Hybrid organic-inorganic main-group metal halide compounds are the subject of intense research owing to their unique optoelectronic characteristics. In this work, we report the synthesis, structure, and electronic and optical properties of a family of hybrid tin (II) bromide compounds comprising guanidinium [G, C(NH2)3 +] and mixed cesium-guanidinium cations: G2SnBr4, CsGSnBr4, and Cs2GSn2Br7. G2SnBr4 has a one-dimensional structure that consists of chains of corner-sharing [SnBr5]2- square pyramids and G cations situated in between the chains. Cs+ exhibits a pronounced structure-directing effect where a mixture of Cs+ and G cations forms mono- and bilayered two-dimensional perovskites: CsGSnBr4 and Cs2GSn2Br7. Furthermore, the flat shapes of the guanidinium cations induce anisotropic out-of-plane tilts of the [SnBr6]4- octahedra in the CsGSnBr4 and Cs2GSn2Br7 compounds. In G2SnBr4, the Sn lone pair is highly stereoactive and favors non-octahedral, that is, square pyramidal coordination of Sn(II). G2SnBr4 exhibits bright broad-band emission from self-trapped excitonic states, owing to its soft lattice and electronic localization. This emission in G2SnBr4 is characterized by a photoluminescence (PL) quantum yield of 2% at room temperature (RT; 75 ± 5% at 77 K) and a fast PL lifetime of 18 ns at room temperature.

N-[3-(Benzyl-dimethyl-aza-nium-yl)prop-yl]-N',N',N'',N''-tetra-methyl-guanidinium bis-(tetra-phenyl-borate).

Project description:In the crystal structure of the title salt, C17H32N4 (2+)·2C24H20B(-), the C-N bond lengths in the CN3 unit of the guanidinium ion are 1.323 (4), 1.336 (5) and 1.337 (5) Å, indicating partial double-bond character in each. The C atom of this unit is bonded to the three N atoms in a nearly ideal trigonal-planar geometry [N-C-N angles = 117.7 (4), 120.9 (3) and 121.4 (3)°] and the positive charge is delocalized in the CN3 plane. The bonds between the N atoms and the terminal C-methyl groups of the guanidinium moiety all have values close to a typical single bond [1.452 (5)-1.484 (6) Å]. In the crystal, C-H⋯π inter-actions are present between guanidinium H atoms and the phenyl rings of both tetra-phenyl-borate ions. This leads to the formation of a two-dimensional supramolecular pattern along the ab plane.

Project description:In the title complex, [Ni(C(16)H(36)N(4))(H(2)O)(2)][Ni(CN)(4)], the [Ni(teta)(H(2)O)(2)](2+) cations (teta = 5,5,7,12,12,14-hexa-methyl-1,4,8,11-tetra-azacyclo-tetra-deca-ne) and [Ni(CN)(4)](2-) anions are arranged in an alternating fashion through electrostatic and N-H?N and O-H?N hydrogen-bonding inter-actions, forming a two-dimensional layered structure. Adjacent layers are linked through weak van der Waals inter-actions, resulting in a three-dimensional supra-molecular network.
