5-Bromophthalazine hemihydrate
The title compound, C(8)H(5)BrN(2)·0.5H(2)O, is a phthalazine derivative synthesized from 3-bromo-benzene-1,2-dicarbaldehyde and hydrazine. The mol-ecule is essentially planar, the deviation from the mean plane of the phthalazine ring being 0.015 (3) Å. The O atom of the solvent water mol-ecule is situated on a twofold rotation axis. In the crystal, O-H⋯N hydrogen bonds and short N⋯Br [2.980 (3...

In the title compound, C(17)H(14)N(2)O(4)S·0.5H(2)O, the mol-ecule, with the exception of the two meth-oxy-phenyl groups, is nearly planar with an r.m.s. deviation of 0.0305 Å. The two 2-meth-oxy-phenyl rings make dihedral angles of 4.1 (3) and 2.3 (3)° with the thia-diazole ring. In the crystal, inter-molecular C-H⋯O and O-H⋯N hydrogen bonds link the mol-ecules.

In the title compound, C(11)H(8)F(2)N(2)O(2)·0.5H(2)O, the dihedral angle between the benzene and isoxazole rings is 8.08 (3)°. In the crystal, the components are linked by O-H⋯N and N-H⋯O hydrogen bonds, in which the water mol-ecule acts as both a donor and an acceptor, into a tape with an R(4) (4)(16) graph-set motif along the a axis. The water mol-ecule is located on a twofold rotation axis....
متن کامل3,5,3′,5′-Tetramethyl-4,4′-bi(1H-pyrazolyl) hemihydrate
In the title compound, C(10)H(14)N(4)·0.5H(2)O, the amino H atom of one of the two pyrazole rings is disordered over its two N atoms in a 1:1 ratio. The pyrazole rings are aligned at 60.1 (1)°. In the crystal, two bipyrazolyl mol-ecules are linked by an N-H⋯N hydrogen bond, generating a dimer; the dimer is connected to the water mol-ecule, which lies on a twofold rotation axis, resulting in the...
متن کاملN-(1-Allyl-1H-indazol-5-yl)-4-methoxybenzenesulfonamide hemihydrate
In the title compound, C17H17N3O3 (.)0.5H2O, the indazole system makes a dihedral angle of 46.19 (8)° with the plane through the benzene ring and is nearly perpendicular to the allyl group, as indicated by the dihedral angle of 81.2 (3)°. In the crystal, the water mol-ecule, disordered over two sites related by an inversion center, forms O-H⋯N bridges between indazole N atoms of two sulfonamide...
