Here's a general approach to making crystals of these compounds:

Start by building the individual molecules using the Builder module in Materials Studio.

Go to Sketch > Insert > Molecule, and then either choose a pre-built molecule or build it manually using the atomic fragments available in the builder.

Adjust the geometry to make sure bond lengths and angles are realistic (use literature values or typical bond lengths and angles).

Once the molecule is built, you'll need to create a crystal structure.

Go to Modules > Build > 3D Atomistic.

Choose Space Group from the available options. For example, you can choose a common space group like P1 if you're unsure about the symmetry requirements, or select a space group that matches your desired crystal symmetry (e.g., P21/c for monoclinic symmetry, etc.).

After defining the space group, you can place the molecule inside the unit cell.

Go to Edit > Symmetry > Add Molecule to Symmetry. This will add the molecule according to the symmetry operations of the chosen space group.

Adjust the positioning, orientation, and packing of the molecule within the unit cell using the Transform tool if needed.

I hope this can help

Good luck
