important position in the field of synthetic chemistry
and a very likely candidate for recycling of waste and
conversion of industrial waste (like formaldehyde, car-
bon monoxide, carbon dioxide, etc.) into useful products
and the most likely candidate to promote ‘‘Green
Chemistry’’.

As we know that the progress of today’s society
depends on the synthesis and development of the
advanced materials, which need consumption of energy
as well as utilization of very toxic solvents and other
chemicals. This all can play havoc with the environment
and life. In addition, it is well known that our earth is a
closed system with limited resources for use. This pro-
vokes an urge of recycling the materials in safest ways,
i.e., to ensure maximum recycling at the expense of
minimum energy.

and it indicated no organic contamination. Water was also doubly dis-
tilled and boric acid was recrystallized twice. Kaolin clay was also
free of any organic contamination.
Finally, our synthetic route to synthesize 1 clearly
proves that hydrothermal routes of synthesis enjoy an
