Crystal structure and fluorescence study of (?-N-[(3,5-dimethyl-1H-pyrrol-2-yl)methyl-idene]-N-{4-[(3,5-dimethyl-1H-pyrrol-2-yl)methyl-idene-aza-nium-yl]phen-yl}aza-nium)bis-[di-fluorido-boron(IV)].

ABSTRACT: The title mol-ecule, C₂₀H₂₀B₂F₄N₄, assumes a planar conformation with all atoms apart from the F atoms lying on the symmetry plane. Each boron atom is four-coordinated by two fluorine atoms, a pyrrole N atom and an imine N atom. Both imine CH=N groups adopt a trans conformation. In the crystal, the mol-ecules self-assemble into a pillar structure through C-H?F hydrogen bonds and ?-? inter-actions. The UV-vis spectrum and fluorescence spectra of the title compound are also reported.

The title mol-ecule, C20H20B2F4N4, assumes a planar conformation with all atoms apart from the F atoms lying on the symmetry plane. Each boron atom is four-coordinated by two fluorine atoms, a pyrrole N atom and an imine N atom. Both imine CH=N groups adopt a trans conformation. In the crystal, the mol-ecules self-assemble into a pillar structure through C-H⋯F hydrogen bonds and π-π inter-actions. The UV-vis spectrum and fluorescence ...[more]

Project description:In an effort to discover novel and potential boron-dipyrromethene (BODIPY) dyes, the title compound, C(19)H(18)BF(2)N(3)O(2), was prepared from 2,4-dimethyl-pyrrole, 4-nitro-benzaldehyde and BF(3)·Et(2)O in a one-pot reaction. There are two independent mol-ecules, A and B, in the asymmetric unit in which the dihedral angles between the benzene ring and boron-dipyrromethene mean plane have significantly different values [82.71?(8)° for mol-ecule A and 73.16?(8)° for mol-ecule B]. Inter-molecular C-H?? inter-actions help to stabilize the crystal structure.

2,4-Dibromo-6-[(E)-({3-[(E)-(3,5-dibromo-2-oxidobenzyl-idene)aza-nium-yl]-2,2-dimethyl-prop-yl}iminium-yl)meth-yl]phenolate.

Project description:In the title mol-ecule, C(19)H(18)Br(4)N(2)O(2), the dihedral angle between the benzene rings is 73.9?(2)°. Two intra-molecular N-H?O hydrogen bonds make S(6) ring motifs. In the crystal, mol-ecules are linked via C-H?O inter-actions, forming chains propagating along the a-axis directon. A short C?Br [3.401?(5)?Å] contact is present in the crystal structure, which is further stabilized by a ?-? inter-action [centroid-centroid distance = 3.739?(3)?Å].

Poly[bis-[?(2)-(dimethyl-aza-nium-yl)methyl-enediphospho-nato]magnesium].

Project description:The title compound, [Mg(C(3)H(10)NO(6)P(2))(2)](n), synthesized by a hydro-thermal method, adopts a one-dimensional polymeric chain structure and is isotypic with the previously reported Cd complex based on the ligand N,N-dimethyl-amino-methane-1,1-diphospho-nic acid (H(4)L). The asymmetric unit contains one half Mg(2+) ion and one H(3)L(-) anion. The unique Mg(2+) ion lies on an inversion center and is octa-hedrally coordinated by O atoms from six phospho-nate groups of four different H(3)L(-) anions. Each H(3)L(-) anion, with one protonated N atom and two phospho-nate OH groups, serves as a tridentate ligand. Two of its six phospho-nate O atoms chelate to a Mg(2+) cation in a bidentate fashion, while a third O atom bridges to a neighbouring Mg(2+) ion. The inter-connection of Mg(2+) ions by the H(3)L(-)anions leads to the formation of a polymer chain along the a axis in which the adjacent Mg(2+) ions are doubly bridged by two equivalent H(3)L(-) anions. These discrete chains are further assembled into a three-dimensional supra-molecular network via O-H?O and N-H?O hydrogen bonds involving the non-coordin-ated phospho-nate O atoms and the protonated N atoms.

2-[(Di-methyl-phenyl-phosphanyl-idene)aza-nium-yl]-5-methyl-benzene-sulfonate benzene monosolvate.

Project description:The title compound, C15H18NO3PS·C6H6, is a rare example of a crystallographically characterized exocyclic phosphiniminium-arene-sulfonate zwitterion, which crystallises as its benzene solvate. The crystal structure shows that the N atom is protonated and that the iminium H atom forms both intra- and inter-molecular hydrogen bonds to the single-bonded sulfonate O atom in an R 2 (2)(4) graph-set motif. The dihedral angle between the aromatic rings in the main molecule is 89.49?(8)°.

2-Hy-droxy-5-[(E)-(1H-indol-3-yl-methyl-idene)aza-nium-yl]benzoate.

Project description:The zwitterionic title compound, C(16)H(12)N(2)O(3), was obtained as a result of the condensation of 5-amino-salicylic acid and 1H-indole-3-carbaldehyde. The whole mol-ecule is roughly planar: the 4-hy-droxy-anilinic group and the 1H-indole-3-carbaldehyde moieties are only slightly twisted, making a dihedral angle of 7.77?(11)°, whereas, the carboxyl-ate group makes a dihedral angle of 3.34?(45)° with the parent 4-hy-droxy-anilinic group. S(6) ring motifs are formed due to intra-molecular O-H?O hydrogen bonding. In the crystal, inter-molecular N-H?O and C-H?O hydrogen bonds build up pseudo-rings with R(1) (2)(4), R(2) (1)(7) and R(2) (2)(14) ring motifs. These pseudo-dimers are further linked by N-H?O hydrogen bonds into a chain extending along [101]. C-H?? inter-actions also occur, along with offset ?-? inter-actions between the anilinic phenyl and the heterocyclic five-membered rings with a centroid-centroid distance of 3.5716?(19)?Å.

Project description:The asymmetric unit of the title compound, C(16)H(12)Cl(4)N(2)O(2), comprises half of a potentially tetra-dentate Schiff base ligand, located about a twofold rotation axis which bis-ects the central C-C bond of the ethane-1,2-diamine group. In the solid state, the compound exists in the zwitterionic form. There are two intra-molecular N-H?O hydrogen bonds making S(6) ring motifs. In the crystal, mol-ecules are linked by C-H?O hydrogen bonds, forming two-dimensional frameworks which lie parallel to (100). There are also short Cl?Cl [3.4395?(9)?Å] contacts present.

2-[(5-Chloro-2-oxidobenzyl-idene)aza-nium-yl]-2-methyl-propane-1,3-diol.

Project description:The title compound, C(11)H(14)ClNO(3), was prepared by the condensation of equimolar quanti-ties of 5-chloro-salicyl-aldehyde and 2-amino-2-methyl-propane-1,3-diol in methanol. In the crystal, it exists in the zwitterionic form, with nominal proton transfer from the phenol group to the imine N atom. This results in the formation of an intra-molecular N-H⋯O hydrogen bond, which generates an S(6) ring. Inter-molecular O-H⋯O hydrogen bonds arise from the hy-droxy groups, forming (001) sheets.

Project description:The asymmetric unit of the title azo-pyrrole-BF2 complex, C12H12BF2N3O, contains two independent mol-ecules, which are linked by an O-H?O hydrogen bond. The dimers are further assembled into a one-dimensional ladder-like structure through O-H?F hydrogen bonds and stabilized by ?-? inter-actions. The ladders are further linked by C-H?? contacts.
