3-Acetyl-6-chloro-2-methyl-4-phenylquinolinium perchlorate
In the title mol-ecular salt, C(18)H(15)ClNO(+)·ClO(4) (-), the quinolin-ium ring system is approximately planar, with a maximum deviation of 0.027 (1) Å. The dihedral angle formed between the mean planes of the quinolinium ring system and the benzene ring is 78.46 (3)°. In the crystal structure, inter-molecular N-H⋯O and C-H⋯O hydrogen bonds link the cations and anions into a three-dimensional...
متن کامل3-Acetyl-2-methyl-4-phenylquinolin-1-ium chloride
An N-H⋯Cl hydrogen bond connects the ions in the title salt, C(18)H(16)NO(+)·Cl(-). The quinolin-1-ium residue is almost planar (r.m.s. deviation = 0.020 Å) but both the acetyl group [O-C-C-C torsion angle = 62.73 (17)°] and adjacent benzene ring [C-C-C-C torsion angle = -104.06 (14)°] are twisted out of this plane; the acetyl and benzene substituents are non-parallel [dihedral angle = 66.16 (7...
متن کامل3-Acetyl-6-chloro-2-methyl-4-phenylquinolinium hydrogen sulfate
In the title salt, C(18)H(15)ClNO(+)·HSO(4) (-), the quinolinium ring system is approximately planar, with a maximum deviation of 0.028 (2) Å, and forms a dihedral angle of 78.43 (4)° with the attached phenyl ring. A pair of inter-molecular O-H⋯O hydrogen bonds links two hydrogen sulfate anions into a dimer, generating a R(2) (2)(8) ring motif. Inter-molecular N-H⋯O hydrogen bonds and C-H⋯O con...
متن کاملMethyl 2-acetamido-2-(1-acetyl-3-hydroxy-2-oxoindolin-3-yl)propanoate
In the title isatin compound, C(16)H(18)N(2)O(6), the pyrrolidine ring adopts an envelope conformation and is inclined at a dihedral angle of 7.31 (5)° with respect to the benzene ring. The acetyl group is disordered over two positions with refined occupancies of 0.503 (4) and 0.497 (4). These groups make dihedral angles of 12.6 (6) and 19.6 (7)° with the pyrrolidine ring. In the crystal struct...
متن کاملTHE CALCIUM BINDING SITES OF THE BAKERS' YEAST TRANSKETOLASE
The calcium binding sites of Bakers' Yeast Transketolase (TK) was elucidated by estimating the pKa values of the functional groups that bind to calcium. These pKa's were found to be 6.25 and 7.2 relating to the pKa's of the two immidazol moieties of histidine residues on the enzyme. The rate of the binding of calcium to the enzyme was obtained separately as a function of pH. Maximum values ...
