2,2'-{[(2,2'-Dieth-oxy-1,1'-binaphthalene-6,6'-di-yl)bis-(4,1-phenyl-ene)]bis-(methan-ylyl-idene)}dimalononitrile.

ABSTRACT: The title compound, C(44)H(30)N(4)O(2), was prepared from 6,6'-dibromo-2,2'-dieth-oxy-1,1'-binaphthalene through a coupling reaction with 4-(4,4,5,5-tetra-methyl-1,3,2-dioxaborolan-2-yl)benzaldehyde followed by a Knoevenagel reaction with malononitrile. The dihedral angle between the symmetry-related naphthalene ring systems is 68.82?(8)° while the dihedral angle between the the naphthalene ring system and the adjacent benzene ring is 16.92?(7)°. Four symmetry-independent mol-ecules which are linked by inter-molecular C-H?? inter-action generate the packing motif in the crystal structure. One of the CN groups is disordered over two sets of sites in a 0.60?(2):0.40?(2) ratio.

Di-?3-acetato-bis-{?-6,6'-dieth-oxy-2,2'-[propane-1,2-diylbis(nitrilo-methanylyl-idene)]diphenolato}dicadmiumdisodium ethanol 0.67-solvate.

Project description:In the crystal of the title compound, [Cd2Na2(C2H3O2)2(C21H24N2O4)2]·0.67C2H6O, the doubly deprotonated Schiff base ligand N,N',O,O'-chelates to the Cd(II) cation, which is also O,O'-chelated by the acetate ion. Two Cd-Schiff base units are connected to two Na(+) atoms to form the tetra-nuclear complex, in which the Cd(2+) and Na(+) cations show distorted octa-hedral coordinations. The asymmetric unit consists of half a tetra-nuclear mol-ecule (lying on an inversion center) and a full tetra-nuclear mol-ecule (lying on a general position) along with a lattice ethanol mol-ecule, which links to the coordinating acetate ion via an O-H?O hydrogen bond. In the crystal, the propyl and ethyl groups of the complex mol-ecule are disordered over two positions in a 1:1 ratio; the ethyl group of the lattice ethanol mol-ecule is also equally disordered over two positions.

Crystal structure and mol-ecular docking study of diethyl 2,2'-({[(1E,1'E)-(hydrazine-1,2-diyl-idene)bis-(methanylyl-idene)]bis-(4,1-phenyl-ene)}bis-(-oxy))di-acetate.

Project description:The title Schiff base, C22H24N2O6, adopts an E configuration. The mol-ecule is planar, the mean planes of the phenyl ring system (r.m.s deviation = 0.0059 Å) forms a dihedral angle of 0.96 (4)° with the mean plane of the phenyl ring moiety (r.m.s deviation = 0.0076 Å). In the crystal, mol-ecules are linked by weak inter-molecular C-H⋯O and C-H⋯N hydrogen bonds into chains extending along the c-axis and b-axis directions, respectively. A mol-ecular docking study between the title mol-ecule and 5-HT2C, which is a G protein receptor and ligand-gated ion channels found in nervous systems (PDB ID: 6BQH) was executed. The experiment shows that it is a good potential agent because of its affinity and ability to stick to the active sites of the receptor.

Crystal structure of 1,1'-{(1E,1'E)-[4,4'-(9H-fluorene-9,9-di-yl)bis-(4,1-phenyl-ene)]bis-(aza-nylyl-idene)bis(methanylyl-idene)}bis-(naphthalen-2-ol) di-chloro-benzene monosolvate.

Project description:The bis-(anil) mol-ecule of the title compound, C47H32N2O2·C6H4Cl2, contains two anil fragments in the enol-enol form, exhibiting intra-molecular O-H⋯N hydrogen bonds. The two hy-droxy-naphthalene ring systems are approximately parallel to each other with a dihedral angle of 4.67 (8)° between them, and each ring system makes a large dihedral angle [55.11 (11) and 48.50 (10)°] with the adjacent benzene ring. In the crystal, the bis-(anil) mol-ecules form an inversion dimer by a pair of weak C-H⋯O inter-actions. The dimers arrange in a one-dimensional column along the b axis via another C-H⋯O inter-action and a π-π stacking inter-action between the hy-droxy-naphthalene ring system with a centroid-centroid distance of 3.6562 (16) Å. The solvent 1,2-di-chloro-benzene mol-ecules are located between the dimers and bind neighbouring columns by weak C-H⋯Cl inter-actions. Theoretical prediction of potential biological activities was performed, which suggested that the title anil compound can exhibit histone de-acetyl-ase SIRT2, histone de-acetyl-ase class III and histone de-acetyl-ase SIRT1 activities, and will act as inhibitor to aspulvinone di-methyl-allyl-transferase, de-hydro-l-gulonate deca-rboxylase and gluta-thione thiol-esterase.
