Viruses belonging to the Flaviviridae family primarily spread through arthropod vectors, and are the major causes of illness and death around the globe. The Flaviviridae family consists of 3 genera which include the Flavivirus genus (type species, yellow fever virus) as the largest genus, the Hepacivirus (type species, hepatitis C virus) and the Pestivirus(More)
The pyrimidine and benzene rings in the title compound, C(10)H(8)N(2)O(2), form a dihedral angle of 71.03 (7)°, with the roughly orthogonal benzene ring being folded towards one of the pyrimidine N atoms. In the crystal, pairs of O-H⋯N hydrogen bonds connect mol-ecules related by twofold symmetry into dimeric aggregates. These associate into a(More)
In the title mol-ecule, C(12)H(10)N(2)O(4), the pyridine and benzene rings are almost orthogonal [dihedral angle = 86.69 (11)°], with the pyridine N atom directed towards the centre of the benzene ring. The -NO(2) [O-N-C-C = -26.1 (3)°] and -OMe [C-O-C-C = 166.5 (2)°] substituents are not coplanar with their respective aromatic rings. In the crystal,(More)

A significant twist is observed in the title molecule, C(11)H(10)N(2)O(2), as seen in the dihedral angle between the pyrazine and benzene rings of 72.79 (8)°. The meth-oxy group is almost coplanar with the benzene ring to which it is attached [C-O-C-C torsion angle = 175.83 (15)°]. Centrosymmetric dimers are formed in the crystal structure which are held(More)
The title mol-ecule, C(12)H(10)N(2)O(3), is twisted, the dihedral angle between the rings being 61.16 (13)°. The nitro group is approximately coplanar with the pyridine ring to which it is attached [O-N-C-C torsion angle = -178.1 (3)°]. Supra-molecular chains along [010] and mediated by C-H⋯O and π-π [centroid(pyrid-yl)-(benzene) distance = 3.8259 (18) Å](More)
A nearly orthogonal relationship is found for the ring systems in the title compound, C(15)H(10)N(2)O(3), with the dihedral angle between the rings being 86.13 (11)°. The nitro group is approximately coplanar with the pyridine ring to which it is connected [the O-N-C-C torsion angle = -1.8 (4)°]. This coplanarity allows for the close approach of these(More)
The complete dinuclear mol-ecule of the title complex, [Cu(2)(CH(3)COO)(4)(C(10)H(8)N(2)O)(2)], is generated by a centre of inversion. The Cu(II) atom is in a distorted octa-hedral coordination geometry defined by four O atoms derived from four bridging acetate ligands, a terminally connected pyrimidine N atom and a Cu atom.
In the title compound, C(11)H(10)N(2)O(2), the aromatic rings are almost orthogonal to each other [dihedral angle = 86.97 (8)°], with the benzene ring orientated to face one of the pyrazine N atoms. In the crystal, centrosymmetrically related pairs are connected via pairs of C-H⋯π inter-actions and the dimeric units thus formed pack into undulating layers(More)
In the title compound, C(11)H(10)N(2)O(2), the benzene ring faces towards one of the pyrimidine N atoms, and is almost orthogonal to the plane through the pyrimidine ring [dihedral angle = 84.40 (14)°]. In the crystal, the presence of C-H⋯π and π-π [centroid-centroid separation = 3.7658 (18) Å] inter-actions leads to a supra-molecular array in the ac plane.(More)
