Description

General description

Crystals of SnCl₂.2H₂O exhibit exhibit monoclinic crystal system and space group P2₁/c.

Application

Tin(II) chloride dihydrate (SnCl₂.2H₂O)may be used in the preparation of indoles. It may be used in the transformation of conjugated dioxolones, conjugated and non-conjugated acetals (dimethoxy and diethoxy acetals) to aldehydes.
It plays the role of a catalyst in the synthesis of 3-aminoimidazo[1,2-a]pyridines. It can be used as precursor for the synthesis of tin dioxide (SnO₂) nanostructures by thermal degradation at temperature between 400-700 under controlled conditions.
