文摘
- •
Twelve different 1,3-bis(4-pyridyl)propane-bridged dicobaloximes have been reported.
- •
TGA, DTA and DSC studies were carried out in order to know the thermal stability and phase transition.
- •
DSC study of these complexes with long alkyl chain reveals two mesomorphic phases.
- •
X-rd study reveal that in the present systems two Co(dmgH)2 are not equivalent.
- •
Crystal packing diagram indicates the presence of extensive intermolecular interactions.
