Abstract
Single crystal to single crystal transformation of a new mercury(II) coordination polymer with ligand 1,4-bis(2-pyridyl)-2,3-diaza-1,3-butadiene (bpdb), [Hg2(µ-bpdb)I4] (1α) to [Hg2(µ-bpdb)(µ-I)2I2]n (1β), has been reported and structures of 1α and 1β were determined by X-ray crystallography. The thermal stability of compounds 1α and 1βwere studied by thermal gravimetric (TG) and differential thermal analyses (DTA). Powder X-ray diffraction experiments showed that the phase transitions described for single crystals also occur in macroscopic powder samples and lead to monophasic products and the crystal-to-crystal transformation described is not reversible.
