1-(6-Fluoro-1,3-benzothia-zol-2-yl)-2-(1-phenyl-ethyl-idene)hydrazine

Synthesis, X-ray characterization, DFT calculations and Hirshfeld surface analysis of thiosemicarbazone complexes of Mn+ ions (n = 2, 3; M = Ni, Cd, Mn, Co and Cu)

Herein we report the synthesis, X-ray characterization, DFT calculations and Hirshfeld surface analysis of seven complexes of transition metal ions with pyridine-based thiosemicarbazone ligands.

1-(6-Chloro-1,3-benzothiazol-2-yl)-2-[1-(4-methoxyphenyl)ethylidene]hydrazine

The asymmetric unit of the title compound, C₁₆H₁₄ClN₃OS, contains two independent mol­ecules (A and B) linked into dimers via N—H⋯N hydrogen bonds. The 1,3-benzothia­zol-2-yl ring system and the benzene ring form dihedral angles of 17.08 (8) and 8.63 (7)° in mol­ecules A and B, respectively.

1-(5-Chloro-6-fluoro-1,3-benzothiazol-2-yl)hydrazine

In the title compound, C₇H₅ClFN₃S, the 1,3-benzothia­zole ring system is nearly planar (r.m.s. deviation = 0.023 Å). In the crystal, mol­ecules are linked via inter­molecular N—H⋯N hydrogen bonds into a two-dimensional network parallel to (100).
