摘要

Two new coordination compounds [Zn(AZT)₄(H₂O) ₂](PA)₂·4H₂O and [Zn(AZT) ₂(H₂O)₄](HTNR)₂·4H ₂O have been prepared by using AZT (3-azido-1,2,4-triazole) as ligands, PA- (picrate) or HTNR- (anion formed by the deprotonation of one of the two hydroxyl-groups of 2,4,6-trinitroresorcinol) as outer anions. The X-ray crystallographic data show that the central zinc(II) ion is coordinated by four N atoms of four AZT molecules and two O atoms of two H₂O molecules in [Zn(AZT)₄(H₂O)₂](PA)₂· 4H₂O. In [Zn(AZT)₂(H₂O)₄](HTNR) ₂·4H₂O, six coordination-atoms come from two N atoms of two AZT molecules and four O atoms of four H₂O molecules. The coordination sites of AZT ligands in both compounds are always 4-N atoms of the triazole rings. H₂O molecules play vital roles in the formation of hydrogen bonds, which contribute to the construction of the crystal structures of both compounds. The offset face-to-face π-π stacking interactions existing in the crystal of [Zn(AZT)₄(H ₂O)₂](PA)₂·4H₂O also contribute to the formation and stability of its crystal structure. TG-DTG and DSC analysis results show that the thermal decomposition processes of [Zn(AZT)₂(H₂O)₄](HTNR)₂· 4H₂O are milder than those of [Zn-(AZT)₄(H ₂O)₂](PA)₂·4H₂O due to the more coordination H₂O molecules and less AZT ligands in the molecular unit of the former compound. Sensitivity tests reveal that [Zn(AZT) ₄(H₂O)₂](PA)₂·4H ₂O has sensitive nature towards heat, whereas [Zn(AZT) ₂(H₂O)₄](HTNR)₂·4H ₂O is insensitive; both compounds are insensitive to friction and impact.
