Crystal Structure,Thermal Decomposition and Properties of Cesium 3,5-Dihydroxy-2,4,6-Trinitrophenolate

摘要

A coordination polymer,cesium 3,5-dihydroxy-2,4,6-trinitro-phenolate ([Cs(DHTNP)]_n),has been synthesized and its crystal structure determined.This crystal belongs to the monoclinic system with space group P_c.Each Cs~+ is coordinated to 12 oxygen atoms from 8 different 3,5-dihydroxy-2,4,6-trinitrophenolate (DHTNP~-) anions,and each DHTNP" anion is coordinated with 8 Cs~+ cations.The oxygen atoms of the phenolic hydroxyl group and from all of the nitro groups of the DHTNP~-anion simultaneously bind to neighboring Cs~-ions.These DHTNP~-molecular chains are interlaced,with the cesium atoms acting as knots,to create an infinite three-dimensional network structure.The molecules are linked by electrostatic interactions and weak
