RESUMO
The title compound, C22H20N4O3S, features two fused six-membered rings linked to a 1,2,3-triazole ring which is attached to an ethyl acetate group. The heterocycle in the benzo-thia-zine residue has an envelope conformation with the S atom being the flap. The conformation of the ethyl acetate side chain, which is directed to the same side of the mol-ecule as the C6 ring of the fused-ring system, may be partially established by a pair of weak intra-molecular C-Hâ¯O(carbon-yl) inter-actions. The three-dimensional packing is aided by inter-molecular C-Hâ¯O and C-Hâ¯N inter-actions.
RESUMO
In the title compound, C15H13NOS, the thia-zine ring adopts a twisted boat conformation and the dihedral angle between the aromatic rings is 86.54â (4)°. In the crystal, mol-ecules are linked by weak C-Hâ¯O inter-actions, resulting in chains along [010].
RESUMO
The imidazopyridine fused ring in the title compound, C(19)H(14)BrN(3), is almost coplanar with the phenyl ring at the 2-position of the five-membered ring [dihedral angle = 2.4â (1). The crystal structure features short Brâ¯Br contacts [3.562â (1)â Å].
RESUMO
The imidazopyridine fused ring in the title compound, C(20)H(16)BrN(3)O·H(2)O, is coplanar with the aromatic ring at the 2-position [dihedral angle = 5.2â (1)°]. In the five-membered imidazo portion, the C-N bond whose C atom is also connected to the pyridine N atom has predominantly double-bond character [1.334â (2)â Å] whereas the C-N bond whose atom is connected to the pyridine C atom has predominantly single-bond character [1.371â (2)â Å]. The water mol-ecule engages in hydrogen bonding with the latter N atom; it is also connected to a symmetry-related water mol-ecule, generating a linear chain structure.
