In the older literature, the lattice constants ,coordinates and other crystallographic details are listed explicitly in the paper, however that cannot be processed or observed using softwares(mercury or any other software). How to observe that can we write the data file manually and if yes then how say for instance for the data in paper J. Chem. Soc. C, 1971,0, 2788-2791. DOI:10.1039/J39710002788
