This what I get from your input:

print('\n-------------------------------')

print('\n rdkit Version : ', rdkit.__version__)

from rdkit import Chem

from rdkit.Chem.Draw import IPythonConsole

from rdkit.Chem import Draw


mol = Chem.MolFromSmiles("FC(C=CC=C1)=C1C2=NN=CO2.IC1=CC=C(OC)C=C1.C(=O)([O-])[O-].[Cs+].[Cs+].C1COCCO1.[Cu+].[I-].CC(C)(C)[C-]1([CH]2=C34P(C5CCCCC5)C6CCCCC6)[CH]7=[CH]3[Fe+2]7189%10%1124[CH]%12=C([CH]9=[CH]%10[C-]%12%11C(C)(C)C)8P(C%13CCCCC%13)C%14CCCCC%14.FC1=C(C2=NN=C(C3=CC=C(OC)C=C3)O2)C=CC=C1",

                         sanitize = True)

Draw.ShowMol(mol)

Output :

File ".../.../.../.../rdkit/Chem/Draw/__init__.py", line 233, in MolToImage
    raise ValueError('Null molecule provided')

ValueError: Null molecule provided

with :

sanitize = False

Output :

Am I doing something wrong ?
