In the crystal structure of the title compound, C(14)H(10)FN(3)O, the plane of the isoxazole ring makes dihedral angles of 35.72 (9) and 30.00 (9)°, respectively, with those of the 4-fluoro-phenyl and pyridine rings. The plane of the 4-fluoro-phenyl ring makes a dihedral angle of 45.85 (8)° with that of the pyridine ring. The crystal structure is stabilized by inter-molecular N-H⋯N hydrogen bon...

The central pyrazole ring in the title compound, C17H16FN3S, adopts an envelope conformation with the methine C atom bearing the 4-fluoro-phenyl substituent as the flap atom. Whereas the tolyl ring is slightly twisted out of the least-squares plane through the pyrazole ring [dihedral angle = 13.51 (11)°], the fluoro-benzene ring is almost perpendicular [dihedral angle = 80.21 (11)°]. The thio-a...

The title compound, C(8)H(11)FN(5) (+)·Cl(-), crystallized with a monoprotonated 1-(4-fluoro-phen-yl)biguanidinium cation and a chloride anion in the asymmetric unit. The biguanidium group is not planar [dihedral angle between the two CN(3) groups = 52.0 (1)°] and is rotated with respect to the phenyl group [τ = 54.3 (3)°]. In the crystal, N-H⋯N hydrogen-bonded centrosymmetric dimers are connec...

Abstract Two lead( ii ) coordination complexes with 2-(4-fluoro-phenyl)-1 H -imidazo[4,5- f ][1,10]phenanthroline formulated as [Pb(L) 2 (tlba) )] ( 1 and [Pb(L)(dpea)] (HTLBA = 2,3,4,5-tetrachlorobenzoic acid, dpea diphenic acid) were synthesized under hydrothermal conditions. In , the neighboring molecules formed into a two-dimensional (2D) layer structure C–Cl⋯π interactions N–H⋯O hydrogen b...

Vol. 106 No. 7/8 Page 1 of 5 ABSTRACT Moloney murine leukaemia virus (M-MuLV) is a member of the retrovirus family. Its cloned reverse transcriptase (RT), similarly to HIV type 1 reverse transcriptase (HIV-1 RT), exhibits DNA-polymerase and ribonuclease H (RNase H) activities capable of converting the single-stranded retroviral RNA genome into double-stranded DNA. The latter is then integrated ...

The title compound, C(19)H(13)F(2)N, was synthesized by an addition reaction of bis-(4-fluoro-phen-yl)methanone with aniline. The dihedral angles formed by the fluoro-benzene rings with the aniline ring are 81.04 (5) and 64.15 (5)°. In the crystal packing, inter-molecular C-H⋯F hydrogen bonds link mol-ecules into zigzag chains parallel to the c axis.

The reaction of 4-fluoro-aniline hydro-chloride, 18-crown-6 and ferric chloride in methano-lic solution yields the title compound, (C(6)H(7)FN)[FeCl(4)]·C(12)H(24)O(6), which has an unusual supramolecular structure. N-H⋯O hydrogen-bonding inter-actions between the NH(3) (+) substituents of the 4-fluoro-anilinium cations and the O atoms of the crown ether mol-ecules result in a rotator-stator-li...
