6-Bromo-2-(4-nitro-phen-oxy)-3-(1-phenyl-ethyl)-3,4-dihydro-1,3,2-benzoxaza-phosphinine 2-oxide.

ABSTRACT: In the title compound, C(21)H(18)BrN(2)O(5)P, the six-membered oxaza-phosphinine ring is in a twist-boat conformation. One of the phosphoryl O atoms is in an equatorial configuation while the other is axial with respect to the oxaza-phosphinine ring. The mean planes of the benzene ring to which the nitro group is attached and the phenyl ring form a dihedral angle of 83.5?(1)°. In the crystal structure, weak inter-molecular C-H?O hydrogen bonds link the mol-ecules into chains along [100].

2-(3-Meth-oxy-phen-yl)-1,3-dihydro-1,3,2-benzodiaza-borole.

Project description:The title compound, C(13)H(13)BN(2)O, is one in a series of 1,3,2-benzodiaza-boroles featuring a 2-meth-oxy-phenyl substitution at the 2-position in the nitro-gen-boron heterocyle. The dihedral angle between the mean planes of the benzodiaza-borole and 2-meth-oxy-phenyl ring systems is 21.5?(1)°. There is an inter-molecular hydrogen bond between one of the NH groups and the meth-oxy O atom. This hydrogen bond leads to an infinite hydrogen-bonded chain colinear with the a axis.

3-(4-Bromo-phen-yl)-3-(4-hydr-oxy-6-oxo-1,6-dihydro-pyrimidin-5-yl)-N-[(S)-1-phenyl-ethyl]propanamide.

Project description:In the mol-ecule of the title compound, C(21)H(20)BrN(3)O(3), the pyrimidine ring is oriented at dihedral angles of 80.87?(3) and 15.99?(3)°, respectively, to the pyrimidine and bromo-phenyl rings. The dihedral angle between the two benzene rings is 88.37?(3)°. In the crystal structure, inter-molecular N-H?O and O-H?N hydrogen bonds link the mol-ecules. A ?-? contact between pyrimidine and phenyl rings [centroid-centroid distance = 3.776?(3)?Å] may further stabilize the structure. The methine H and the methyl C and H atoms are disordered over two positions and were refined with occupancies of 0.522?(13) and 0.478?(13).

5-Bromo-2-[5-(4-nitro-phen-yl)-3-phenyl-4,5-dihydro-1H-pyrazol-1-yl]pyrimidine.

Project description:In the title pyrazoline compound, C(19)H(14)BrN(5)O(2), the essentially planar pyrazoline and pyrimidine rings [maximum deviations = 0.013 (1) and 0.009 (1) Å, respectively] are inclined slightly to one another, making a dihedral angle of 10.81 (10)°. The nitro-benzene unit is almost perpendicular to the attached pyrazoline ring, as indicated by the dihedral angle of 84.61 (8)°. In the crystal structure, inter-molecular C-H⋯N contacts link the mol-ecules into dimers in an anti-parallel manner. These dimers are further linked into one-dimensional chains along the b axis via C-H⋯O contacts. The crystal structure is consolidated by three different inter-molecular π-π inter-actions [range of centroid-centroid distances = 3.5160 (11)-3.6912 (11) Å].

3-(6-Methyl-2-pyrid-yl)-2-phenyl-3,4-dihydro-1,3,2-benzoxaza-phosphinine 2-oxide.

Project description:In the title compound, C(19)H(17)N(2)O(2)P, the six-membered 1,3,2-oxaza-phosphinine ring adopts a boat conformation with the phosphoryl O atom in an equatorial position. The dihedral angle between the 6-methyl-2-pyridyl and phenyl groups is 75.5?(1)°. These substituents are trans to each other, and are oriented at angles of 57.2?(1) and 74.8?(1)°, respectively, to the benzene ring. The crystal structure is stabilized by intra- and inter-molecular hydrogen bonds. The phosphoryl O atom participates in inter-molecular C-H?O inter-actions with the neighbouring mol-ecules, forming centrosymmetric R(2) (2)(14) dimers.

3,4-Bis(4-bromo-phen-yl)-N-phenyl-maleimide.

Project description:In the title mol-ecule, C(22)H(13)Br(2)NO(2), the three benzene rings are arranged in a propeller-like fashion around the central malemide ring, making dihedral angles of 48.2?(4), 30.2?(4) and 34.8?(4)° with the malemide ring. The C-C single-bond lengths connecting benzene groups and maleimide are significantly shorter [C-C = 1.468?(9) and 1.478?(9)?Å] than a typical Csp(3)-Csp(3) single bond, indicating partial conjugation between the benzene and the mal-eimide. A weak non-classical C-H?O hydrogen bond helps to stabilize the crystal structure.

3-Bromo-methyl-4-meth-oxy-2-(2-nitro-phen-yl)-9-phenyl-sulfonyl-9H-carbazole.

Project description:In the title compound, C26H19BrN2O5S, the carbazole tricycle is essentially planar, with the largest deviation being 0.126 (3) Å for the C atom connected to the nitro-phenyl group. The carbazole moiety is almost orthogonal to the benzene rings of the adjacent phenyl-sulfonyl and nitro-phenyl groups, making dihedral angles of 85.43 (15) and 88.62 (12)°, respectively. The mol-ecular conformation is stabilized by two C-H⋯O hydrogen bonds involving the sulfone group, which form similar six-membered rings. In the crystal, mol-ecules symmetrically related by a glide plane are linked in C(6) chains parallel to [001] by C-H⋯O hydrogen bonds formed with the participation of the nitro group. The chains are reinforced by additional C-H⋯π inter-actions.
