Just wondering how i can calculate molecular descriptors for heavy metal complexes for example vitamin b12 contains a cobalt in its structure? Using MOE software as far as i am aware as soon as i wash the molecules it will remove the heavy metal leaving the structure without the metal which i would like to keep! I know people in the literature often remove compounds like these in their datasets but was wondering if it is actually possible to include them and calculate descriptors for the complex as a whole. Thanks for any thoughts, comments, suggestions! Danielle
