Hi folks,
I just wonder if there are any chemistry drawing software to draw a general structure of a crystal?

What I am working on is Organo-Lead perovskite with ABX₃ structure. I just need two pictures showing a general structure of two phases (the tetragonal and the orthorhombic phase) . I know the bond angles of the different position of the bondings but I cannot download the .cif crystal information from the paper as their crystal database needs to pay for registration. I only need a very SIMPLE structures of the two phases. Can chemdraw/ Avagagro do that? I tried to draw with ChemDraw and Chem3D but the crystals looked so ugly.

Any help or suggestion would be greatly appreciated!!! Thanks!!
