Crystal structures of potassium tri-fluorido-(4-meth-oxy-phen-yl)borate and potassium tri-fluorido(4-fluoro-phen-yl)borate.

ABSTRACT: The title compounds, K(+)·C7H7BF3O(-), (I), and K(+)·C6H4BF4 (-), (II), are mol-ecular salts containing para-substituted phenyl-tri-fluorido-borate anions. In each compound, the B atom adopts a distorted tetra-hedral BCF3 geometry. Despite their different compositions and space groups, the irregular KF8 coordination polyhedra of the potassium cations in the structures are almost identical. These polyhedra share faces and edges, generating infinite (010) layers in (I) and infinite (001) layers in (II). In (I), adjacent layers are stacked in an AAA… fashion, whereas in (II), they are stacked in an ABAB… sequence.

Project description:In the title compounds, C14H9F4NO, (I), C14H9BrF3NO, (II), and C14H9F3INO, (III), the two benzene rings are inclined to one another by 43.94?(8)° in mol-ecule A and 55.66?(7)° in mol-ecule B of compound (I), which crystallizes with two independent mol-ecules in the asymmetric unit, but by only 10.40?(12)° in compound (II) and 12.5?(2)° in compound (III). In the crystals of all three compounds, N-H?O hydrogen bonds link the mol-ecules to form chains propagating along the a-axis direction for (I), and along the b-axis direction for (II) and (III). In the crystal of (I), -A-B-A-B- chains are linked by C-H?O hydrogen bonds, forming layers parallel to (010). Within the layers there are weak offset ?-? inter-actions present [inter-centroid distances = 3.868?(1) and 3.855?(1)?Å]. In the crystals of (II) and (III), the chains are linked via short halogen-halogen contacts [Br?Br = 3.6141?(4)?Å in (II) and I?I = 3.7797?(5)?Å in (III)], resulting in the formation of ribbons propagating along the b-axis direction.

1-(4-Meth-oxy-phen-yl)-2-[4-(tri-fluoro-meth-yl)phen-yl]-1H-phenanthro[9,10-d]imidazole.

Project description:In the title compound, C29H19F3N2O, a phenanthroline-fused imidazole tetra-cyclic system, the fused benzene rings deviate slightly from the central ring and make dihedral angles with this ring of 3.47?(8) and 3.05?(8)°. The tri-fluoro-methyl-phenyl ring is roughly coplanar with the phenanthroline-fused imidazole tetra-cyclic system [dihedral angle = 11.02?(6)°], while the meth-oxy-phenyl ring is almost perpendicular [dihedral angle = 87.65?(6)°]. There are intra-molecular C-H ?? inter-actions involving the meth-oxy-phenyl ring and the central phenanthroline ring, as well as an inter-molecular C-H?? inter-action involving the phenanthroline ring. In addition, there is an inter-molecular ?-? inter-action involving the central phenanthroline ring and the tri-fluoro-methyl-phenyl ring [centroid-centroid distance = 3.685?(2)?Å], as well as C-H?N inter-actions linking the mol-ecules into dimers.

(<i>Z</i>)-3-({[3-Meth-oxy-5-(tri-fluoro-meth-yl)phen-yl]imino}meth-yl)benzene-1,2-diol.

Project description:The title compound, C15H12F3NO3, crystallizes with one mol-ecule in the asymmetric unit. The mean planes of the two phenyl rings of the Schiff base moiety, bearing the OH groups and the imine group, respectively, are inclined to each other by 4.91?(1)°. In the crystal, mol-ecules are linked via pairs of bifurcated O-H?O hydrogen bonds between the phenol OH groups, forming inversion dimers with an R 1 2(5) ring motif. The structure exhibits also intra-molecular O-H?N and C-H?F hydrogen-bonding inter-actions. Hirshfeld surfaces analysis and two-dimensional fingerprint plots were applied to qu-antify the inter-molecular inter-actions. The three F atoms of the tri-fluoro-methyl group are disordered over two sets of sites, with occupancy factors of 0.578?(8) and 0.422?(8). The crystal studied was refined as an inversion twin.

N-(4-Meth-oxy-phen-yl)-6-methyl-2-phenyl-5-{[4-(tri-fluoro-meth-yl)anilino]meth-yl}pyrimidin-4-amine.

Project description:The title compound, C26H23F3N4O, crystallizes with two symmetry-independent mol-ecules in the asymmetric unit, denoted A and B, which differ mainly in the rotation of the meth-oxy-phenyl ring. The -CF3 group of mol-ecule B is disordered by rotation, with the F atoms split over two sets of sites; the occupancy factor for the major component is 0.853?(4). The dihedral angles between the pyrimidine ring and the attached phenyl, meth-oxy-phenyl and tri-fluoro-methyl-phenyl rings are 8.1?(2), 37.5?(2) and 70.7?(2)°, respectively, in mol-ecule A, and 9.3?(2), 5.3?(2) and 79.7?(2)° in mol-ecule B. An intra-molecular N-H?N hydrogen bond occurs in each mol-ecule. In the crystal, two crystallographically independent mol-ecules associate into a dimer via a pair of N-H?N hydrogen bonds, with a resulting R 2 (2)(12) ring motif and ?-? stacking inter-actions [centroid-centroid distance = 3.517?(4)?Å] between the pyrimidine rings. For the A mol-ecules, there are inter-molecular C-H?O hydrogen bonds between an aryl C atom of meth-oxy-phenyl ring and a meth-oxy O atom of an adjacent mol-ecule. A similar inter-action is lacking in the B mol-ecules.
