In the title compound, C25H20FN3S, two independent mol-ecules comprise the asymmetric unit, which differ in the relative orientation of the fluoro-benzene ring with respect to the pyrazole ring to which it is attached [dihedral angles = 89.39 (17) and 75.23 (16)° in the two mol-ecules]. Each pyrazole ring adopts an envelope conformation with the methine C atom being the flap atom. There are add...

In the crystal structure of the title mol-ecule, C(13)H(15)NO(5)S, the S and N atoms of the thia-zine ring exihibit the maximum deviations from the least-squares plane of 0.3008 (6) and 0.3280 (7) Å, respectively. The ring therefore adopts a half chair conformation. The thia-zine ring is twisted by an angle of 13.29 (7)° with respect to the aromatic ring. The isopropyl substituent is oriented a...

In the title mol-ecule, C(21)H(15)ClN(4)S, the triazoloisoquinoline ring system is approximately planar, with an r.m.s. deviation of 0.054 (2) Å and a maximum deviation of 0.098 (2) Å from the mean plane for the triazole ring C atom that is bonded to the thia-zole ring. The thia-zole and benzene rings are twisted by 66.36 (7) and 56.32 (7)°, respectively, with respect to the mean plane of the t...

The asymmetric unit of the enanti-omerically pure title compound, C18H18N2O3S, comprises two independent mol-ecules (A and B) having almost identical conformations. When overlayed, the alignment-r.m.s. deviation value is 0.30 Å. The six-membered heterocycle has a twisted half-chair conformation in both mol-ecules. The O atom on the S atom of the ring is pseudo-axial on the thia-zine ring and tr...

The asymmetric unit of the title salt, C19H25N2OS(+)·C4H3O4 (-) [systematic name: (S)-3-(2-meth-oxy-pheno-thia-zin-10-yl)-N,N,2-tri-methyl-propanaminium hydrogen maleate], comprises two (S)-levomepromazine cations and two hydrogen maleate anions. The conformations of the two cations are similar. The major difference relates to the orientation of the meth-oxy substituent at the pheno-thia-zine r...

In the title compound, C(29)H(20)F(3)NO(3)S, the thia-zolidine ringadopts a half-chair conformation. The pyrrolidine and two five-membered carbocyclic rings are in envelope conformations with the spiro C atoms at the flaps. The trifluoro-methyl-substituted benzene ring forms dihedral angles of 62.37 (14) and 87.40 (14)° with the benzene rings of the dihydro-1H-indene units. The two benzene ring...

The asymmetric unit of the title compound, C(25)H(14)ClFN(4)S, contains two independent mol-ecules (A and B). Each mol-ecule consists of five rings, namely chloro-phenyl, fluoro-phenyl, 1H-pyrazole, thia-zole and benzonitrile. In mol-ecule A, the 1H-pyrazole ring makes dihedral angles of 52.54 (8), 35.96 (8) and 15.43 (8)° with respect to the attached chloro-phenyl, fluoro-phenyl and thia-zole ...

In the title compound, C(20)H(15)N(3)O(3)S, an intra-molecular C-H⋯O hydrogen bond generates an S(6) ring motif. The chromene ring system is inclined at dihedral angles of 14.21 (9) and 9.91 (10)°, respectively, with respect to the thia-zole and benzene rings. The thia-zole ring makes a dihedral angle of 24.06 (11)° with the benzene ring. In the crystal structure, O-H⋯O hydrogen bonds link the ...

In the crystal structure of the title compound, C(21)H(14)ClN(3)OS, mol-ecules assemble into inversion dimers via pairs of N-H⋯N hydrogen bonds involving the N-H hydrogen of the thia-zine ring and the N atom of the pyridine ring. There is a close intra-molecular contact [2.570 (2) Å] between the carbonyl O atom of the benzamide and the S atom of the puckered thia-zine ring. The title compound c...

The title mol-ecular salt, C21H25N2O5S(+)·Cl(-), crystallizes with two ion pairs in the asymmetric unit. The cations have similar conformations (r.m.s. overlay fit = 0.40 Å), with one of them showing disorder of the terminal methyl group of the ester in a 0.72 (2):0.28 (2) ratio. In the first cation, the 3,4-dimeth-oxy-substituted phenyl ring subtends a dihedral angle of 88.38 (7)° with the pyr...
