Avogadro 1 is not under active development, the repository was archived in September 2021. Development of Avogadro 2 is being done at https://github.com/openchemistry/avogadrolibs. Avogadro is an advanced molecular editor designed for cross-platform use in computational chemistry, molecular modeling, bioinformatics, materials science, and related areas.
Problem:
When loading cif file from Cambridge Crystallographic database (CSD Entry: PMCIIR, link), distance between Ir and Ir atoms in dimer is displayed as 4.72 A in Avogadro.
In internal Cambridge Crystallographic database viewer 4.072 A. XCrysDen also measures distance between Ir and Ir atoms as 4.072 A. Avogadro 1.1.1/1.2.0 seems to have a bug (maybe, incorrect cif reading?)
