Di-2-pyridyl ketone 4-methyl-4-phenyl­thio­semicarbazone

Varughese Philip; V. Suni; M.R. Prathapachandra Kurup

The molecule of the title compound, C(19)H(17)N(5)S, adopts a Z configuration about the azomethine bond and exists as the thione tautomer. The overall structure of the molecule is distributed in four different planes. An intramolecular hydrogen bond involving the pyridyl N atom and the H atom attached to the hydrazine N atom leads to the formation of a six-membered ring.

Acta Crystallographica Section C-crystal Structure Communications | 2005

Bis(μ-phenyl 2-pyridyl ketone N4,N4-butane-1,4-diylthiosemicarbazonato)bis[chlorocopper(II)]

A. Sreekanth; V. Suni; Rohith P. John; Munirathinam Nethaji; M.R. Prathapachandra Kurup

The title compound, [Cu2(C17H17N4S)2Cl2], exhibits a dimeric structure related by a centre of symmetry. The monomers are linked to each other by the longest Cu-S apical distance observed to date among Cu(II) square-pyramidal complexes of N4-substituted thiosemicarbazones. Each Cu(II) atom deviates from the coordination square plane, which contains the pyridyl and imine N atoms, the thiolate S atom and the Cl- anion, towards the S atom of the adjacent monomer. The dimers pack in a zigzag manner through the crystal.
