Fac-{2-[Bis(2-amino-eth-yl)amino]-ethanaminium}trichloridorhodium(III) chloride hemihydrate.

ABSTRACT: The crystal structure of the title compound, [Rh(C(6)H(19)N(4))Cl(3)]Cl·0.5H(2)O, is isotypic with the previously reported Ru analogue. The structure contains two crystallographically independent [Rh(Htren)Cl(3)](+) cations with a facial tridentate coordination of the monoprotonated tren ligand [tren = tris-(2-amino-eth-yl)amine], leading to an overall distorted octahedral coordination environment around the Rh(III) atom. In one of the two cations, the ethyl-ene groups of the two chelate rings as well as the non-coordinating ethyl-ammonium group are disordered over two sets of sites [0.579?(3):0.421?(3) occupancy ratio]. A series of N-H?Cl and O-H?Cl hydrogen bonds stabilizes the structure.

Project description:In the title compound, C(6)H(19)N(4) (+)·Cl(-)·CH(2)Cl(2), the non-H atoms of the ammonium ion show non-crystallographic C(3) symmetry. The chloride ion is embedded in a framework of seven crystallographically independent hydrogen bonds (five N-H?Cl and two C-H?Cl), which form layers parallel to the (100) plane. Two N---H...N bonds also occur.

Bis{2-[(guanidinoimino)-meth-yl]phenolato-?(3) N,N',O}cobalt(III) chloride hemihydrate.

Project description:The title compound, [Co(C8H9N4O)2]Cl·0.5H2O, is a solvatomorph of the corresponding trihydrate. Unlike in the structure of the latter compound, there are two different cations in the asymmetric unit of the title compound. The ligand mol-ecules are deprotonated at the phenol O atom and octa-hedrally coordinate the Co(III) atoms through the azomethine N and phenolate O atoms in a mer configuration. In the crystal, the cations, chloride ions and lattice water mol-ecules are linked by N-H?O, N-H?Cl, O-H?Cl and O-H?O inter-actions, forming a two-dimensional network parallel to (10-1).

Crystal structure of (E)-4-{4-[eth-yl(2-hydroxy-eth-yl)amino]-styr-yl}-1-methyl-pyridinium nitrate hemihydrate.

Project description:The asymmetric unit of the title compound, C18H23N2O(+)·NO3 (-)·0.5H2O, contains two independent 4-{4-[eth-yl(2-hy-droxy-eth-yl)amino]-styr-yl}-1-methyl-pyridin-1-ium cations, two nitrate anions and one lattice water mol-ecule. In the cations, the pyridine ring is twisted with respect by 7.98?(12) and 18.42?(10)° to the benzene ring. In the crystal, the cations, the anions and the lattice water mol-ecules are linked by O-H?O hydrogen bonds and weak C-H?O hydrogen bonds, forming a three-dimensional supra-molecular architecture. ?-? stacking occurs between pyridine and benzene rings of adjacent cations, the centroid-centroid distances being 3.8169?(15) and 3.8663?(14)?Å. In the crystal, one of the independent cations is disordered, the central vinyl unit and the terminal hy-droxy-lethyl group being disordered over two sets of sites with site occupancy factors of 0.600?(6) and 0.400?(6).

(Z)-N-(1-Eth-oxy-ethyl-idene)-2,6-bis-(propan-2-yl)anilinium chloride hemihydrate.

Project description:In the title compound, C(16)H(26)NO(+)·Cl(-)·0.5H(2)O, the asymmetric unit consists of two independent cations, their respective chloride anions and a solvent water mol-ecule. Together they form a discrete crescent-shaped entity linked by hydrogen bonds from the central water atom to two Cl(-) ions and from the latter to two protonated imine groups. The geometries of the two independent cations are essentially the same. The planar N=C(O)CH(3) groups in each (r.m.s. deviations = 0.0011 and 0.0026?Å) form dihedral angles of 75.28?(5) and 79.10?(4)° with the benzene rings. In one cation, the methyl atoms of one of the isopropyl groups were modeled as disordered over two sets of sites, with refined occupancies of 0.589?(17) and 0.411?(17).

Project description:In the title complex, [Ni(C(11)H(16)N(3)O)]Cl·2H(2)O, the Ni(II) ion is coordinated within a distorted square-planar environment. In the crystal, inter-molecular N-H?Cl, N-H?O, O-H?O, O-H?Cl and weak C-H?O hydrogen bonds link the components into a two-dimensional network parallel to (001).

Project description:The mol-ecular structure of the title compound, C(26)H(32)N(3)S(+)·PF(6) (-), shows a protonated guanidyl group bridged by an ethyl-ene linker with a tritylsulfanyl unit. The guanidinium (gua) unit displays charge delocalization over the three N-C(gua) bonds. The N-C-C-S group shows a folded nonplanar conformation with a torsion angle of 158.4?(1)°. In the crystal, the cation and anion are linked by an N-H?F inter-action.

?-Carbonato-bis-(bis-{2-[(diethyl-amino)-meth-yl]phen-yl}bis-muth(III)).

Project description:The mol-ecular structure of the title compound, [Bi(2)(C(11)H(16)N)(4)(CO(3))], consists of a symmetrically bridging carbonato group which binds two [2-Et(2)NCH(2)C(6)H(4)](2)Bi units that are crystallographically related via a twofold rotation axis bis-ecting the carbonate group. The two Bi atoms and two of the C atoms directly bonded to bis-muth are quasi-planar [deviations of 0.323?(1) and 0.330?(9)Å for the Bi and C atoms, respectively] with the carbonate group. The remaining two ligands are in a trans arrangement relative to the quasi-planar (CBi)(2)CO(3) system. The metal atom is strongly coordinated by the N atom of one pendant arm [Bi-N = 2.739?(6)?Å], almost trans to the O atom, while the N atom of the other pendant arm exhibits a weaker intra-molecular inter-action [Bi?N = 3.659?(7)?Å] almost trans to a C atom. If both these intra-molecular N?Bi inter-actions per metal atom are considered, the overall coordination geometry at bis-muth becomes distorted square-pyramidal [(C,N)(2)BiO cores] and the compound can be described as a hypervalent 12-Bi-5 species. Additional quite short intra-molecular Bi?O inter-actions are also present [3.796?(8)-4.020?(9)?Å]. Inter-molecular associations through weak ?(6)?Bi inter-actions [Bi?centroid of benzene ring = 3.659?(1)?Å] lead to a ribbon-like supra-molecular association.

Project description:In the title hydrated mol-ecular salt, C(4)H(14)N(2)O(2+)·C(2)O(4) (2-)·H(2)O, the oxalate dianion is almost planar (r.m.s. deviation = 0.020?Å). In the crystal, the components are linked by N-H?O(water), N-H?O(oxalate) O-H(ammonium)?O(oxalate), O-H(water)?O(oxalate) and O-H(water)?O(ammonium) hydrogen bonds, thereby forming a complex three-dimensional packing motif.

Bis[2-((4,6-dimethyl-pyrimidin-2-yl){2-[(4,6-dimethyl-pyrimidin-2-yl)sulfan-yl]eth-yl}amino)-eth-yl] disulfide.

Project description:Bis[2-(4,6-dimethyl-pyrimidin-2-ylsulfan-yl)eth-yl]amine under hydro-thermal conditions has unexpectedly been transformed into the title compound, C(32)H(44)N(10)S(4). In the title mol-ecule, the zigzag 3,10-diaza-6,7-disulfanyldodecyl skeleton has two dimethyl-pyrimidinylsulfanyl groups at both ends, and the aza atoms each carry a dimethyl-pyrimidinyl unit. The N atoms in the skeleton show a planar coordination.

Project description:In the title GaIII complex compound with pentetic acid, [Ga(C14H20N3O10)(H2O)]·3H2O, the GaIII centre is bound in a slightly distorted octa-hedral coordination sphere by two amine N atoms, three carboxyl-ate O atoms and one water O atom. The complex mol-ecule exists as a zwitterion. In the crystal, the complexes are linked to each other via O-H⋯O and C-H⋯O hydrogen bonds, forming layers parallel to (001). Three uncoordinating water mol-ecules link the complex layers via O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds, forming a three-dimensional network.
