Looking forward to hearing your thoughts on this. Best regard

Hi Lukas, according to the source code:https://github.com/rdkit/rdkit/blob/master/External/CoordGen/CoordGen.h double coordgenScaling = 50.0; the default scaling factor, actually more like a "shrinking factor" seems to be 50, producing bond lengths of 1A. For 1.5A bond lengths, you would need

Dear all, this seems trivial, but it may also be worth checking the sanity of original melting point data, crystallographers sometimes enter the melting point in degree Celsius, when degree Fahrenheit is expected, so cross checking with the crystallization temperature etc. can be quite useful.
