“…In the late 1970s, the first crystal structure of the simple d -camphor-10-sulfonate of copper was established . In addition, to the best of our knowledge, only the crystal structures of Cu(II), Ni(II), Cd(II), Zn(II), Mg(II), and Ca(II) camphorsulfonates have hitherto been determined. − However, data concerning the crystal size and other physical properties, which could imply their potential usage, are scanty in the literature, except in the cases of magnesium and calcium. , There is a lot of published scientific work on growing and creating large crystals, some of them very inspiring − with the beauty and possible use of the compounds.…”
