A series of hitherto unreported piperidone embedded α,β-unsaturated ketones were synthesized efficiently in ionic solvent and evaluated for cholinesterase inhibitory activities against acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) enzymes. Most of the synthesized compounds displayed good enzyme inhibition; therein compounds 7i and 7f(More)
In the title compound, C(17)H(11)F(3)O(2), the dihydro-indene ring is approximately planar with a maximum deviation of 0.024 (2) Å and makes a dihedral angle of 3.17 (8) Å with the adjacent benzene ring. In the crystal, mol-ecules are inter-connected by C-H⋯O inter-actions, forming an infinite chain along the c axis.
In the title compound, C(26)H(28)N(4) (2+)·2PF(6) (-), the complete cation is generated by a crystallographic twofold axis. The benz-imidazole ring is almost planar (r.m.s. deviation = 0.0207 Å) and makes dihedral angles of 50.12 (2)° with its symmetry-related component and 65.81 (2)° with the central benzene ring. In the crystal, mol-ecules are linked into(More)
In the title compound, C(14)H(8)Cl(2)N(2)O, the dihedral angles between the plane of the oxadiazole ring and those of the benzene rings are 2.3 (1) and 9.5 (1)°. In the crystal, mol-ecules are linked into chains along the c axis by C-H⋯Cl inter-actions. These chains are stacked along the a axis.
In the title compound, C(15)H(14)N(2)O(3), the dihedral angle between the benzene rings is 66.56 (5)°. In the crystal, N-H⋯O, O-H⋯O and C-H⋯O inter-actions link the mol-ecules into a three-dimensional network. A π-π inter-action, with a centroid-centroid distance of 3.628 (6) Å, helps to establish the packing.
In the crown ether ring of the title compound, C(20)H(24)O(6)·2C(6)H(3)N(3)O(7)·3H(2)O, the O-C(H(2))-C(H(2))-O torsion angles indicate a gauche conformation of the ethyl-eneoxy units, while the C-O-C-C torsion angles indicate planarity of these segments; the dihedral angle between the two benzene rings is 44.53 (13)°. In both picric acid mol-ecules, one of(More)
The asymmetric unit of the title compound, [Ru3(C19H17P)(C25H22P2)(CO)9], consists of two independent mol-ecules. The bis-(di-phenyl-phosphan-yl)methane ligand bridges an Ru-Ru bond and the benzyl-diphenyl-phosphane ligand binds to the third Ru atom. The Ru-Ru bond cis to the benzyl-diphenyl-phosphane ligand is the longest of the three Ru-Ru bonds in both(More)
The complete mol-ecule of the title compound, C(20)H(19)NO(5)S(2), is generated by a crystallographic twofold axis and the O atom and N-H group attached to the central benzene ring are statistically disordered. The dihedral angle between the central and terminal benzene rings is 56.91 (5)° and that between the terminal benzene rings is 29.80 (5)°. In the(More)
In the title compound, [Cr(C(18)H(12)F(3)P)(2)(CO)(4)], the Cr atom is octa-hedrally coordinated by four carbonyl ligands and the two tertiary phosphanes that are trans to each other. The Cr atom and two carbonyl groups are on a twofold axis. The benzene rings attached to the phospho-rus atom make dihedral angles of 80.32 (5), 52.91 (5) and 83.80 (5)° with(More)
