How would we draw the following compound:
[Cr(H2O)4Cl2]Cl2.H2O

Does somebody want to do a video showing this?

For instructions on how to upload images, videos, etc., see viewtopic.php?f=176&t=3916

I have attached a video showing how to draw the compound.
Hope it helps!

I'm sorry. I did not see your post until now, but I will introduce myself at the beginning of next Monday's lecture.

Would we ever deal with lone pairs or only bonds?
What does it mena for a ligand to make multiple bonds when drawing it?

Do we always have to separate the Cl2 that were outside the brackets? (The Cl2 is still considered a part of the complex, correct?)

When drawing coordination compounds we show only bonds.
See my lecture notes discussing polyvalent ligands. These are ligands (molecules) that can bind the same transition metal cation in more than one location.
The 2 Cl- are counterions to the cation (the transition metal complex). They are separate anions, Cl-, and they are outside the coordination sphere. Meaning they are outside the transition metal complex.
