4-(4-Bromo-phenyl-hydrazono)-1-(5-bromo-pyrimidin-2-yl)-3-methyl-2-pyrazolin-5-one.

ABSTRACT: The asymmetric unit of the title compound, C(14)H(10)Br(2)N(6)O, contains two crystallographically independent mol-ecules. The pyrazole ring of one mol-ecule makes dihedral angles of 22.0?(3) and 3.5?(3)° with the pyrimidine and benzene rings, respectively; the corresponding values in the other mol-ecule are 9.2?(3) and 2.1?(3)°, respectively. The mol-ecules are linked by N-H?O, C-H?N and C-H?Br hydrogen bonds.

The asymmetric unit of the title compound, C(14)H(10)Br(2)N(6)O, contains two crystallographically independent mol-ecules. The pyrazole ring of one mol-ecule makes dihedral angles of 22.0 (3) and 3.5 (3)° with the pyrimidine and benzene rings, respectively; the corresponding values in the other mol-ecule are 9.2 (3) and 2.1 (3)°, respectively. The mol-ecules are linked by N-H⋯O, C-H⋯N and C-H⋯Br hydrogen bonds. ...[more]

Project description:The fused pyrazole and pyrimidine rings in the title compound, C22H19BrN4O, are almost coplanar, their planes being inclined to one another by 2.08 (13)°. The dihedral angles formed by the mean plane of the fused ring system and the phenyl and benzene rings are 16.21 (4) and 82.84 (4)°, respectively. An intra-molecular N-H⋯N hydrogen bond is observed. In the crystal, mol-ecules form inversion dimers via pairs of C-H⋯O hydrogen bonds. π-π inter-actions, with centroid-centroid distances of 3.4916 (9) Å, connect the dimers into a three-dimensional network.

3,3-Bis(4-bromo-phenyl-sulfan-yl)-1-methyl-piperidin-2-one.

Project description:In the title compound, C18H17Br2NOS2, the conformation of the piperidin-2-one ring is based on a half-chair with the methyl-ene C atom diagonally opposite the N atom being 0.649?(3)?Å above the plane of the remaining five atoms (r.m.s. deviation = 0.1205?Å). The S atoms occupy axial and bis-ectional positions, and the dihedral angle between the benzene rings of 59.95?(11)° indicates a splayed disposition. Helical supra-molecular chains along the b axis sustained by C-H?O inter-actions is the major feature of the crystal packing. The chains are connected into a three-dimensional architecture by C-H?Br and C-H?? inter-actions.

Methyl 4-[N-(5-bromo-pyrimidin-2-yl)carbamo-yl]benzoate.

Project description:In the title compound, C(13)H(10)BrN(3)O(3), the pyrimidine and benzene rings are twisted with an inter-planar angle of 58.4 (1)°. The secondary amide group adopts a cis conformation with an H-N-C-O torsion angle of 14.8 (1)°. In the crystal, mol-ecules are connected into inversion dimers via pairs of N-H⋯N hydrogen bonds, generating an R(2) (2)(8) motif. The dimers are further connected through a C-Br⋯O inter-action [3.136 (1) Å and 169.31 (1)°] into a chain along [110]. Weak C-H⋯N hydrogen bonds between the methyl benzoate groups and pyrimidine rings are also observed in the crystal structure.

2-Bromo-1-(4-methyl-phen-yl)-3-phenyl-prop-2-en-1-one.

Project description:In the crystal structure of the title compound, C(16)H(13)BrO, the two benzene rings are twisted from each other with a dihedral angle of 52.55?(9)°. Both an intra-molecular C-H?Br hydrogen bond, which generates an S(6) ring motif, and a short Br?O contact [2.9907?(19)?Å] may influence the conformation of the mol-ecule. The crystal packing is stabilized by weak inter-molecular C-H?O inter-actions.

The crystal structure is stabilized by Br?Br inter-actions [3.4549?(11)?Å].

Project description:The conformations of the N-H and C=O bonds in the SO(2)-NH-CO-C group of the title compound (N4BPSTMAA), C(11)H(14)BrNO(3)S, are trans to each other, similar to what is observed in N-(4-chloro-phenyl-sulfon-yl)-2,2,2-trimethyl-acet-amide (N4CPSTMAA) and 2,2,2-trimethyl-N-(4-methyl-phenyl--sulfon-yl)acetamide (N4MPSTMAA). The bond para-meters in N4BPSTMAA are similar to those in N4CPSTMAA, N4MPSTMAA, N-aryl-2,2,2-trimethyl-acet-amides and 4-bromo-benzene-sulfonamide. The benzene ring and the SO(2)-NH-CO-C group in N4BPSTMAA form a dihedral angle of 82.8?(1)°, comparable with the values of 82.2?(1)° in N4CPSTMAA and 71.2?(1)° in N4MPSTMAA. N-H?O hydrogen bonds form a centrosymmetric ring characterized by an R(2) (2)(8) motif.
