Abstract:
Chemistry occupies a unique middle position in the scientific arena, between
physics and mathematics on the one side and biology, ecology, sociology and
economics on the other [1]. Chemistry is the science of matter and of its
transformations, and life is its highest expression [2]. According to reductionist
thinking biology is reducible into chemistry, chemistry into physics, and ultimately
physics into mathematics. Reductionism implies the ease of understanding one level
in terms of another.The work presented this thesis comprises synthesis and characterization of
suitably substituted thiocarbohydrazone and carbohydrazone ligand building blocks, self-assembled metallosupramolecular square grid complexes as well as some di/multinuclear complexes.
The primary aim was the deliberate syntheses of some novel transition metal framework
complexes, mainly metallosupramolecular coordination square grids by self-assembly
and their physico-chemical characterization. The work presented, however, also
include synthesis and characterization of four mononuclear Ni(II) complexes of two
thiosemicarbazones, which we carried out as a preliminary and supporting study. Based on the present work we would like to conclude that the carbohydrazones, thiocarbohydrazones and their coordination framework complexes of transition metals are promising systems for wide application in science and technology varied from physics to biotechnology. Novel classes of materials and biologically important potential compounds
open up further scope of researches and we hopefully welcome any sort of related research to make this work more valuable.
