In the title compound, [Fe(C(5)H(5))(C(24)H(18)N(3)O(2)S)], the pyrazoline ring adopts a twist conformation. The thia-zole ring forms dihedral angles of 83.7 (2) and 34.4 (2)° with the benzene ring of the benzodioxole ring and the fused phenyl ring, respectively. The mol-ecular conformation is stabilized by an intra-molecular C-H⋯π inter-action. The crystal packing features inter-molecular C-H⋯...

In the title compound, C(8)H(7)ClN(4)S(2), the thia-zole ring is essentially planar [r.m.s. deviation = 0.0011 (2) Å] and conformation of the thia-zolidine ring is twisted on the C-C bond. The C=N bond has a Z configuration.

In the title mol-ecule, C(15)H(10)ClNO(4)S, the heterocyclic thia-zine ring adopts a half-chair conformation, with the S and N atoms displaced by 0.527 (7) and 0.216 (7) Å, respectively, on opposite sides of the mean plane formed by the remaining ring atoms. The mol-ecular structure is consolidated by an intra-molecular O-H⋯O inter-action and the crystal packing is stabilized by N-H⋯O and C-H⋯O...

Significantly large Stokes shifts and enhanced solid state emissions were achieved in a novel series of asymmetric core-expanded aza-BODIPY analogues, 4a-4d, synthesized by a facile and scalable two-step reaction in high yields.

The title compound, [Fe(2)(C(15)H(12)N(2)S(3))(CO)(6)], was prepared as an aza-dithiol-atodiiron model for the active site of [FeFe]-hydrogenase. The Fe(2)S(2) core adopts a butterfly shape, with each metal having a pseudo square-pyramidal geometry. The N-substituted aza-dithiol-ate is μ(2)-κ(4)S,S':S,S'-coordinated to the Fe(CO)(3) moieties to form two fused six-membered rings with different c...

The title compound C(14)H(29)N(4) (+)·I(-) salt, was obtained by the reaction of cage adamanzane-type aminal 1,3,6,8-tetra-aza-tricyclo-[4.3.1.1(3,8)]undecane with heptyl iodide. In the cation, the bond lengths and angles are within normal ranges, except for one N-C(ring) bond distance of 1.542 (3) Å, which is unexpectedly long compared with related compounds. In the crystal, ions are linked th...

In the title compound, C(13)H(17)NO(2)S, the thia-zolidine-1,4-dione ring adopts an envelope conformation with the S atom lying 0.631 (4) Å out of the plane formed by the other four ring atoms; the phenyl ring is almost perpendicular [88.74 (8)°] with respect to the ring C-C-N-C atoms and the butyl chain is in a fully extended conformation. In the crystal, a supra-molecular two-dimensional arra...
