Crystal structure of di-chlorido-{N (1)-phenyl-N (4)-[(quinolin-2-yl-?N)methylidene]benzene-1,4-diamine-?N (4)}mercury(II).

ABSTRACT: In the mononuclear title complex, [HgCl2(C22H17N3)], synthesized from the quinoline-derived Schiff base N (1)-phenyl-N (4)-[(quinolin-2-yl)methyl-idene]benzene-1,4-di-amine (PQMBD) and HgCl2, the coordination sphere around the Hg(2+) atom is distorted tetra-hedral, comprising two Cl atoms [Hg-Cl = 2.3487?(14) and 2.4490?(15)?Å] and two N atom donors from the PQMBD ligand, viz. the quinolyl and the imine N atom [Hg-N = 2.270?(4) and 2.346?(4)?Å, respectively]. The dihedral angle between the two benzene rings attached to the amino group is 43.7?(3)°. In the crystal, N-H?Cl and C-H?Cl hydrogen bonds, as well as ?-? stacking inter-actions between one phenyl ring and the pyridine ring of the quinoline moiety of an adjacent mol-ecule [centroid-to-centroid separation = 3.617?(4)?Å] are observed, resulting in a three-dimensional network.

Crystal structure of di-μ-chlorido-bis(chlorido-{N (1)-phenyl-N (4)-[(pyridin-2-yl-κN)methyl-idene]benzene-1,4-di-amine-κN (4)}mercury(II)).

Project description:The whole mol-ecule of the title complex, [Hg2Cl4(C18H15N3)2], is generated by inversion symmetry. It was synthesized from the pyridine-derived Schiff base N-phenyl-N'-[(pyridin-2-yl)methyl-idene]benzene-1,4-di-amine (PPMBD). The five-coordinated Hg(2+) ions have a distorted square-pyramidal environment defined by two N atoms, viz. the imine and the other pyridyl [Hg-N = 2.467 (6) and 2.310 (6) Å, respectively] belonging to the bidentate imino-pyridine ligand, and three Cl atoms [Hg-Cl = 2.407 (2), 2.447 (2) and 3.031 (2) Å]. The longest Hg-Cl bond is bridging about the inversion centre. In the ligand, the central ring and pyridine ring are oriented at a dihedral angle of 8.1 (4)°, while the planes of the pyridine ring and the terminal phenyl ring are oriented at a dihedral angle of 53.8 (4)°. In the crystal, mol-ecules are linked by N-H⋯Cl and C-H⋯Cl hydrogen bonds, forming sheets parallel to (001).

Crystal structure of N (1)-phenyl-N (4)-[(quinolin-2-yl)methyl-idene]benzene-1,4-di-amine.

Project description:In the title compound, C22H17N3, the dihedral angles between the central benzene ring and the terminal phenyl ring and quinoline ring system (r.m.s. deviation = 0.027 Å) are 44.72 (7) and 9.02 (4)°, respectively, and the bond-angle sum at the amine N atom is 359.9°. In the crystal, the N-H group is not involved in hydrogen bonding and the mol-ecules are linked by weak C-H⋯π inter-actions, generating [010] chains.

N-[(E)-4-Chloro-benzyl-idene]-N'-phenyl-benzene-1,4-diamine.

Project description:The title compound, C(19)H(15)ClN(2), adopts an E configuration with respect to the position of the chloro-benzene and diphenyl-amine groups on the C=N azomethine bond. The mol-ecule is not planar, the central six-membered ring making angles of 12.26?(10) and 44.18?(11)° with the 4-chloro-phenyl and phenyl rings, respectively. In the crystal structure, weak C-H?? inter-actions contribute to the stabilization of the packing.

N,N'-Bis(di-phenyl-meth-yl)benzene-1,4-di-amine.

Project description:The complete mol-ecule of the title compound, C32H28N2, is generated by crystallographic inversion symmetry. The dihedral angles between the central aromatic ring and the pendant adjacent rings are 61.37 (16) and 74.20 (14)°. The N-H group does not participate in hydrogen bonds and there are no aromatic π-π stacking inter-actions in the crystal.

catena-Poly[[chloridomercury(II)]-?-1,4-diaza-bicyclo-[2.2.2]octane-?N:N'-[chlorido-mercury(II)]-di-?-chlorido].

Project description:In the title coordination polymer, [Hg(2)Cl(4)(C(6)H(12)N(2))](n), each Hg(II) center within the chain is four-coordinated by one terminal Cl atom, two bridging ?(2)-Cl atoms, and one N-atom donor from a ?(2)-1,4-diaza-bicyclo-[2.2.2]octane (?(2)-daco) ligand in a distorted tetra-hedral geometry. The daco ligand acts as an end-to-end bridging ligand and bridges adjacent Hg(II) centers, forming a chain running along [001]. Weak C-H?Cl hydrogen-bonding inter-actions link the chains into a three-dimensional network. Comparison of the structural differences with previous findings suggests that the space between the two N donors, as well as the skeletal rigidity in N-heterocyclic linear ligands, may play an important role in the construction of such supra-molecular networks.

Crystal structures of 2,5-di-azido-1,4-phenyl-ene di-acetate and 2,5-di-azido-1,4-phenyl-ene dibutyrate.

Project description:The asymmetric units of the title compounds, C10H8N6O4, (I), and C14H16N6O4, (II), each contain half of the respective mol-ecule which is completed by inversion symmetry. The two molecules differ in the ester moiety (acetate versus butyrate) and the crystal symmetry is different, i.e. triclinic for (I) and monoclinic for (II). The di-azido-phenyl-ene moieties are essentially planar [maximum deviation of 0.0216?(7)?Å for (I) and 0.0330?(14)?Å for (II)], and the ester functionalities are almost perpendicular to these planes, making dihedral angles of 79.93?(3)° for (I) and 79.42?(6)° for (II). In the crystals of both (I) and (II), there are no significant inter-molecular inter-actions present.

1,4-Bis(4-chloro-phenyl-seleno)-2,5-di-methoxy-benzene.

Project description:The title compound, C(20)H(16)Cl(2)O(2)Se(2), utilizes the symmetry of the crystallographic inversion center. Mol-ecular chains are formed through symmetric C-H⋯Cl inter-actions around inversion centers, mimicking the commonly observed symmetric hydrogen-bonded dimer pattern often found in carboxylic acids.

Di-chlorido-(4-{[(quinolin-2-yl)methyl-idene]amino}phenol-?(2) N,N')mercury(II).

Project description:In the mononuclear title complex, [HgCl2(C16H12N2O)], synthesized from the phenolic Schiff base 4-[(quinolin-2-yl-methyl-idene)amino]-phenol (QMAP), the coordination geometry around Hg(2+) is distorted tetra-hedral, comprising two Cl atoms [Hg-Cl = 2.3565?(12) and 2.5219?(12)?Å] and two N-atom donors from the QMAP ligand, viz. one imine and the other quinoline [Hg-N = 2.392?(2) and 2.237?(2)?Å, respectively]. In the crystal, O-H?Cl hydrogen bonds generate a chain structure extending along the c-axis direction. Weak C-H?Cl and ?-? stacking inter-actions [minimum ring centroid separation = 3.641?(3)?Å] give an overall layered structure lying parallel to (001).

Crystal structure of di-chlorido-[2-(di-phenyl-phosphan-yl)-3,4,5,6-tetra-fluoro-benzene-1-thiol-ato-?(2) P,S]gold(III).

Project description:The title compound, [Au(C18H10F4PS)Cl2], crystallizes as neutral mol-ecules, with the Au(III) atom coordinated by two Cl atoms and by the P and S atoms of the bidentate phosphanyl thiol-ate ligand, in a slightly distorted square-planar environment. The mol-ecules are linked into centrosymmetric dimers via long axial Au-Cl bonds of 3.393?(4)?Å. This axial Au-Cl distance is longer than is usually seen, although one other example has been given. Dimer formation may explain the unexpectedly low solubility of the compound in common polar solvents. There is also a separate inter-molecular Au-F contact of 3.561?(6)?Å, but this distance seems too long to be regarded as a bond. Two putative C-H?F hydrogen bonds appear to link the dimers into sheets parallel to (110). There is a short inter-molecular F?F contact of 2.695?(10)?Å between two dimers related by the twofold axis.

Bis[2-phenyl-1-(phenyl-iminio)isoindo-line] di-?-chlorido-bis-[dichloridopalladate(II)] benzene disolvate.

Project description:In the title compound, (C(20)H(17)N(2))(2)[Pd(2)Cl(6)]·2C(6)H(6), the dichloride-bridged [Pd(2)Cl(6)](2-) anion lies across an inversion center with each Pd(II) ion in a slightly distorted square-planar environment. In the crystal structure, two cations and an anion are connected via N-H?Cl hydrogen bonds between the NH groups of the iminioisoindoline cations and terminal Cl atoms of a hexa-chloridodipalladate(II) anion. The Pd-Cl distance of the terminal chloride engaged in hydrogen bonding is slightly longer than the Pd-Cl distance of the adjacent terminal chloride which is not involved in hydrogen bonding.
