ABSTRACT: In the crystal structure of the title compound, CH(6)NO(+)·Cl(-), the cations and anions are linked by N-H?Cl and O-H?Cl hydrogen bonds into an undulating layer motif [Schläfli symbol: 4(8).6(8).8(2)]. All non-H atoms lie on a mirror plane.
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.
Project description:In the title compound, C(6)H(14)N(2) (2+)·Cl(4)I(-)·Cl(-), the dication and the anions lie on special positions. The dication has mm2 symmetry with two bonded C atoms and the two N atoms located on a crystallographic mirror plane parallel to bc, and with a mirror plane parallel to ab passing through the mid points of the three C-C bonds. In the square-planar Cl(4)I(-) anion, two Cl atoms and the I atom are located on the mm2 axis; the other two Cl atoms are disordered over two postions of equal occupancy (0.25) across the mirror parallel to the ab plane. The Cl(-) anion is located on the mm2 axis. The crystal structure is stabilized by inter-molecular N-H?Cl hydrogen bonds.
Project description:In the title compound, [BaCl(C(12)H(24)O(6))(H(2)O)(3)]Cl, the Ba(II) atom, the coordinating and free Cl(-) anions, one coordinating water mol-ecule and two O atoms of an 18-crown-6 mol-ecule lie on a mirror plane. The environment of the ten-coordinate Ba(2+) ion is defined by one Cl atom, three water mol-ecules and six O atoms from the macrocyclic ether. The macrocycle adopts a conformation with an approximate D(3d) symmetry. In the crystal, O-H?Cl hydrogen bonds link the complex cations and Cl(-) anions into a two-dimensional network parallel to (010). An intra-molecular O-H?Cl hydrogen bond is also present.
Project description:In the title gem-dinitro-azetidinium chloride salt, C3H6N3O4(+)·Cl(-), the cations and anions lie on a mirror plane. The azetidine ring is virtually planar, with a mean deviation from the plane of 0.0569?Å. The dihedral angle between the two nitro groups is 90.00?(5)°. In the crystal, the ions are linked by N-H?Cl interactions, forming a chain along the c-axis direction, and C-H?O inter-actions, forming a layer parallel to (010).
Project description:The title compound (C(5)H(14)NO)(4)[Cu(2)(CH(3)COO)(4)Cl(2)]Cl(2), consists of a pair of Cu(II) ions bridged by four acetate groups, resulting in a Cu(2)(CH(3)COO)(4) unit, four (3-hydroxy-prop-yl)dimethyl-ammonium cations (two crystallographically independent pairs) and two chloride anions. The Cu atoms at both termini are bonded to chloride anions. The latter are hydrogen bonded to one of the two pairs of crystallographically independent (3-hydroxy-prop-yl)dimethyl-ammonium cations. The Cu(2)(CH(3)COO)(4) unit is located on a crystallographic inversion center, and the geometry around each metal center is close to octa-hedral. The Cl-Cu-Cu angles are nearly linear [177.48?(2)°] and the Cu-O bond lengths are in the range 1.9712?(18)-1.9809?(19)?Å. The Cu?Cu separation between the two acetate-bridged Cu(II) centers is 2.6793?(8)?Å. The packing of the crystal structure is dominated by N-H?Cl hydrogen bonding between the ammonium groups and the chloride anions, as well as by O-H?O and O-H?Cl hydrogen bonds. One of the 3-hydroxypropyldimethylammonium cations shows orientational disorder with an occupancy ratio of 0.812?(4): 0.188?(4).
Project description:The title compound, [(CH(3))(3)NH](2)[Sn(C(6)H(5))(2)Cl(4)], consists of [(CH(3))(3)NH](+) cations and [SnPh(2)Cl(4)](2-) anions in which the Sn atom, located on a centre of inversion, is bonded to four Cl atoms and two phenyl rings, giving an octa-hedral geometry with the phenyl rings in trans positions. In the crystal, the cations and the anions are connected by N-H?Cl hydrogen bonds and C-H?Cl inter-actions.
Project description:The title compound, C(4)H(10)N(+)·Cl(-), was obtained as a decomposition product from 2,6-bis-(pyrrolidin-yl)pyridine. The anion lies on the same cristallographic mirror plane as the N atom of the cation, the complete cation being generated by mirror symmetry. The anions and cations are connected by N(+)-H?Cl(-) hydrogen bonds into chains along . The pyrrolidinium cation is puckered in an envelope conformation E(N1).
Project description:The crystal structure of the title compound, [Co(3)(C(5)H(9)O(2))(6)O(CH(4)O)(3)]Cl, consists of trinuclear Co(III) complex cations and chloride anions. The Co(III) cation has site symmetry m, and is coordinated by four oxygen atoms from four bridging pivalate groups, one central O anion and a methanol oxygen atom, forming a distorted octa-hedral geometry. The coordinated methanol mol-ecule is located on a crystallographic special position, the C and O atoms being located on the mirror plane. The central O anion lies in the crystallographic position, and acts as a ?(3)-O bridge, linking three equivalent Co(III) cations and generating the oxo-centered trinuclear Co(III) complex. The chloride anion, which acts as the counter-ion, is located on crystallographic position. O-H?Cl hydrogen bonding between the Cl anion and hydroxyl group of the coordinated methanol mol-ecule links the mol-ecules into a supra-molecular network.
Project description:In the title compound, C(18)H(24)NO(2) (+)·Cl(-), the absolute configuration of the new stereogenic centre (the C atom with a CH(2)OH substituent) was unambiguously determined to have an R configuration. The dihedral angle between the two aromatic rings is 30.82?(2)°. Inter-molecular N-H?Cl and O-H?Cl hydrogen bonds and intra-molecular N-H?O hydrogen bonds stabilize the crystal structure.
Project description:The crystal structure of the title compound, C(9)H(20)NO(+)·Cl(-)·0.33(H(3)O(+)·Cl(-)), is composed of 4-hydr-oxy-2,2,6,6-tetra-methyl-piperidinium cations, hydroxonium cations and chloride anions, which are connected via O-H?O, O-H?Cl and N-H?Cl hydrogen bonding. The 4-hydr-oxy-2,2,6,6-tetra-methyl-piperidinium cation and one of the two crystallographically independent chloride anions are located on a mirror plane. The hydroxonium cation is located on a threefold axis and the second crystallographically independent chloride anion is located on a sixfold rotoinversion axis. Due to symmetry, the hydroxonium cation is disordered over two positions.
