6-(4-Amino-phen-yl)-2-eth-oxy-4-(2-thien-yl)nicotinonitrile.

ABSTRACT: In the title nicotinonitrile derivative, C(18)H(15)N(3)OS, the central pyridyl ring makes dihedral angles of 25.22?(10) and 24.80?(16)° with the 4-amino-phenyl and thio-phene rings, respectively. The thio-phene ring is disordered over two orientations by rotation around the C(thio-phene)-C(pyridine) bond; the occupancies are 0.858?(2) and 0.142?(2). The eth-oxy group is slightly twisted from the attached pyridyl ring [C-O-C-C torsion angle = 171.13?(16)°]. In the crystal structure, mol-ecules are linked by N-H?N hydrogen bonds into chains along [010]. These chains are stacked along the a axis. C-H?? weak inter-actions involving the thio-phene ring are observed.

Project description:The mol-ecule of the title nicotinonitrile derivative, C(22)H(19)BrN(2)O(2), is non-planar, the central pyridine ring making dihedral angles of 7.34?(14) and 43.56?(15)° with the 4-bromo-phenyl and 4-ethoxy-phenyl rings, respectively.

A weak intra-molecular C-H?N inter-action generates an S(5) ring motif. In the crystal structure, the mol-ecules are linked by weak inter-molecular C-H?N inter-actions into screw chains along the b axis. These chains stacked along the a axis. ?-? inter-actions with centroid-centroid distances of 3.8724?(16) and 3.8727?(16)?Å are also observed.

6-(4-Bromo-phen-yl)-2-eth-oxy-4-(2,4,6-trimethoxy-phen-yl)nicotinonitrile.

Project description:In the asymmetric unit of the title nicotinonitrile derivative, C(23)H(21)BrN(2)O(4), there are two non-planar independent mol-ecules. The central pyridine ring makes dihedral angles of 9.05?(7) and 77.06?(7)°, respectively, with the 4-bromo-phenyl and 2,4,6-trimethoxy-phenyl rings in one mol-ecule, whereas the corresponding values are 5.96?(7) and 82.37?(7)° in the other. All the three meth-oxy groups are essentially in the plane of the attached benzene ring [C-O-C-C angles = 2.99?(19), 4.8?(2) and -6.2?(2)° in one mol-ecule, and 2.69?(18), 176.73?(15) and 1.3?(2)° in the other]. The eth-oxy group is slightly twisted in one mol-ecule [C-C-O-C = 173.84?(12)°], whereas it is coplanar with the pyridine ring in the other [C-C-O-C = -177.23?(13)°]. Weak intra-molecular C-H?N inter-actions generate S(5) ring motifs. In the crystal structure, the mol-ecules are linked by weak inter-molecular C-H?N and C-H?O inter-actions into a supra-molecular three-dimensional network in such a way that the nicotinonitrile units of neighboring mol-ecules are stacked in an anti-parallel manner along the c axis. The crystal is further stabilized by C-H?? inter-actions.

6-(4-Bromo-phen-yl)-2-eth-oxy-4-(2,4,5-trimethoxy-phen-yl)nicotinonitrile.

Project description:There are two mol-ecules in the asymmetric unit of the title compound, C(23)H(21)BrN(2)O(4), which differ in the conformation of their ethoxy residues, i.e. almost co-planar with the pyridine ring in one mol-ecule [C-O-C-C = -174.0?(2)°] but almost perpendicular in the other [C-O-C-C = 92.8?(3)°]. The dihedral angles between the central pyridine ring and the 4-bromo-phenyl and 2,4,5-trimethoxy-phenyl rings are 11.05?(12) and 63.78?(12)°, respectively, in one mol-ecule; the corres-ponding angles in the other mol-ecule are 30.38?(13) and 65.38?(13)°, respectively. In the crystal structure, pairs of mol-ecules are arranged in a face-to-face sandwich structure which further stacks along the b axis. The crystal packing features C-H?? inter-actions and Br?O [3.5417?(17)?Å], Br?C [3.748?(3)?Å], C?N [3.376?(4)?Å] and C?O [3.351?(3)-3.409?(3)?Å] contacts. Finally, ??? inter-actions [centroid?centroid distances = 3.6346?(19) and 3.6882?(19)?Å] are observed.

Bis{(R)-1-(3-amino-sulfonyl-4-meth-oxy-phen-yl)-N-[2-(2-eth-oxy-phen-oxy)eth-yl]propan-2-aminium} adipate tetra-hydrate.

Project description:The title compound, 2C20H29N2O5S(+)·C6H8O4 (2-)·4H2O, which was found to be optically active, is a relatively rare example of a chiral compound crystallizing in the triclinic crystal system. The dihedral angles between the phenyl rings of the cations are 60.03?(15) and 62.03?(16)°, while the C atoms of the anion are almost coplanar (r.m.s. deviation 0.085?Å) and all trans to each other. In the crystal, the components are connected by an extensive network of N-H?O and O-H?O hydrogen bonds. The sulfonamide groups link the cations into pairs via two N-H?O hydrogen bonds about the pseudo-inversion centre, leading to the formation of R 2 (2)(8) rings. The anions are stacked in between four cationic pairs. Pairs of water mol-ecules bridge the larger building units, forming hydrogen bonds with the remaining two O atoms of the anion.

Ethyl N-[2-(4-phen-oxy-phen-oxy)eth-yl]carbamate.

Project description:The title compound, C(17)H(19)NO(4), which is a non-toxic insect growth regulator with the common name fenoxycarb, contains two independent and conformationally different mol-ecules in the asymmetric unit. Although the inter-ring dihedral angles are similar [62.21?(15) and 63.00?(14)°], the side-chain orientations differ. In the crystal, the mol-ecules are linked through N-H?O hydrogen-bonding associations, giving chains which extend along [110], while intra- and inter-molecular aromatic C-H?? inter-actions give sheet structures parallel to [110].
