5-Chloro-6-hydroxy-7,8-dimethylchroman-2-one
In the title mol-ecule, C(11)H(11)ClO(3), the fused pyran ring adopts a half-chair conformation. In the crystal, inter-molecular O-H⋯O hydrogen bonds link mol-ecules into chains along [100]. These chains are inter-connected by weak inter-molecular C-H⋯O contacts which generate R(2) (2)(8) ring motifs, forming sheets parallel to (001). Tetra-gonal symmetry generates an equivalent motif along b. ...
متن کاملChannel-forming solvates of 6-chloro-2,5-dihydroxypyridine and its solvent-free tautomer 6-chloro-5-hydroxy-2-pyridone.
On crystallization from CHCl3, CCl4, CH2ClCH2Cl and CHCl2CHCl2, 6-chloro-5-hydroxy-2-pyridone, C5H4ClNO2, (I), undergoes a tautomeric rearrangement to 6-chloro-2,5-dihydroxypyridine, (II). The resulting crystals, viz. 6-chloro-2,5-dihydroxypyridine chloroform 0.125-solvate, C5H4ClNO(2).0.125CHCl3, (IIa), 6-chloro-2,5-dihydroxypyridine carbon tetrachloride 0.125-solvate, C5H4ClNO(2)..0.125CCl4, ...
متن کامل[5-Chloro-2-hydroxy-N′-(2-oxidobenzylidene)benzohydrazidato]pyridinecopper(II)
In the title complex, [Cu(C(14)H(9)ClN(2)O(3))(C(5)H(5)N)], the Cu(II) ion exhibits a distorted trans-CuN(2)O(2) square-planar geometry arising from the O,O,N-tridentate ligand and a pyridine mol-ecule. An intra-molecular O-H⋯N hydrogen bond occurs. In the crystal structure, weak inter-molecular C-H⋯π inter-actions generate a chain. The crystal studied was an inversion twin.
متن کاملCrystal structure of 6-chloro-5-(2-chloroethyl)-3-(propan-2-ylidene)indolin-2-one
The title compound, C13H13Cl2NO, has a 3-(propan-2-yl-idene)indolin-2-one core with a Cl atom and a chloro-ethyl substituent attached to the aromatic ring. Two atoms of the aromatic ring and the chloro-ethyl substituent atoms are disordered over two sets of sites with a refined occupancy ratio of 0.826 (3):0.174 (3). In the crystal, mol-ecules are linked by pairs of N-H⋯O hydrogen bonds, formin...
متن کامل2-[(5-Chloro-2-hydroxybenzylidene)amino]-3′,6′-bis(diethylamino)spiro[isoindoline-1,9′-xanthen]-3-one
The title compound, C(35)H(35)ClN(4)O(3), resulted from a spiro-lactam ring closure of rhodamine B dye. The xanthene ring system is approximately planar [r.m.s. deviation = 0.050 (9) Å for the xanthene ring]. The dihedral angles formed by the spiro-lactam and 5-chloro-2-hy-droxy-benzene rings with the xanthene ring system are 87.9 (7) and 79.1 (7)°, respectively.
