资源简介：
Crystal structures of 10 spiro-derivatives of 1,3-thiazine
were
determined by X-ray diffraction technique. Molecular conformational
states, packing architecture, and hydrogen bond networks were studied
using graph set notations. Selected compounds were grouped within
two classes with chains and dimer crystal structure organization.
The sublimation thermodynamic aspects of the spiro-derivatives of
1,3-thiazine were investigated via temperature dependence of vapor
pressure using the transpiration method. Thermophysical study of fusion
processes of the molecular crystals was carried out and relationships
between thermodynamic characteristics of sublimation (fusion) processes
and crystal structure parameters were obtained. The influence of various
molecular fragments on packing crystal energy was analyzed.
