Dear Avogadro users:
I am a new user of Avogadro, and recently I have employed it to draw and display molecular structures. When I opened a structure from a .cif file, some bonds can be displayed, but others were not displayed (shown in the figures). I want to know how to control the bond tolerability between two given kinds of atoms. Thanks for your attention!
Best Wishes!
Yours iampcd
Avogadro 1.2 doesn’t have control over that. In Avogadro 1.9x (2.0 betas) you can control those tolerances. (The reason for the ‘missing’ bonds in Avogadro 1.2 is that it will refuse to connect atoms beyond the expected valence.)
Dear ghutchis:
How can I get the Avogadro 1.9x?
For example; https://www.openchemistry.org/downloads/
(Seems like 1.93 didn’t include Windows / Mac binaries for some reason.)
1.94 will be released fairly soon, including an announcement here.
