Inorganic salt error in the newest version

In the new version, there is no way to present inorganic salt such as SnCl2. Since Sn has multiple valence, the presentation of SnCl₂ in ionic form is tricky. If simply put 2+ on an Sn atom, the IJC will automatic change Sn to SnH₂^2+,  not the Sn²⁺ as expected. However, in the older version of IJC, the hydrogen can be removed by manually assign the valence number on Sn atom. The Sn²⁺ can be presented correctly by assign valence number 2 on the Sn and it looks like this Sn²⁺ (v2). The mol file of this form is OK to most of cheminformatics softwares.

However, in the current version, this trick is not working. Even if I manully assign the valence number 2 to the Sn atom, the Sn²⁺ is still presented as SnH₂²⁺ and, consequently, all the calculations of SnCl2 is wrong.

Could you please fix this problem? 

Hello,

I have looked into the problem and what you describe indeed seems as a bug. I will forward this to the Marvin Support who are responsible for Marvin Sketch features.

All the best

Hello,

We will fix this issue by 6.2.1, until the fix you can assign zero valence on the Sn atom to fix this problem.
