Hi Steven,
Chimera cannot handle small-molecule CIF files, only macromolecular CIF (mmCIF) files.  You could try our ChimeraX program (in particular the 1.6 release candidate) which can handle many small-molecule CIFs.  https://www.cgl.ucsf.edu/chimerax/

Dear Chimera Team,
 
I’m unable to open the CIF file for a structure that we had done in 2018 and am getting the error shown on the attached jpeg. I am also attaching the CIF file downloaded from CCSD which comes from our original paper:
 
Steven T. Frey, Hillary A. Ramirez*, Manpreet Kauer, and Jerry P. Jasinski.  “Crystal structure of a seven-coordinate manganese(II) complex with tris(pyridin-2-ylmethyl)amine (TMPA),” Acta Crystallographica, 2018, E74, 1075-1078. https://doi.org/10.1107/S2056989018009611.
 
I’d like to be able to open the file in Chimera so that I can produce an ORTEP drawing for another paper. Can you help me figure out what the problem is?
 
Thanks, Steve Frey
