lone pairs on central atoms with expanded octets

Is there any way to show lone pairs on central atoms (in simple molecules) that have expanded octets using MarvinSketch? I'm thinking of SF4, XeF2, etc?





Thanks,

Dear Pete,





It seems possible. I would recommend You this example: http://www.chemaxon.com/marvin/examples/applets/sketch/studentexam/index.html


The desktop application also can be costumized to provide this functionality: first, switch off Edit - Preferences - Structure - Automatic lone pair calculation, then switch on View - Misc - Lone pairs. The increase lone pairs button can be added to the "Tools" toolbar in view - customize - toolbars - add ...


I hope it answers your question If we can help you any further, please do not hesitate to contact us.
