This is a small molecule CIF format file, not an mmCIF (macromolecular CIF) file. ChimeraX only reads mmCIF files. Chimera could handle some CIF files but probably poorly. Small molecule CIF files are used for crystallography of organic and inorganic small molecules, typically less than 50 atoms. It would be significant work to try to support CIF files. They don't even represent x,y,z coordinates the same way, instead using fractional (0-1) unit cell coordinates.

Unfortunately both CIF and mmCIF formats use the same file suffix and don't have a standard header value that says what format is being used. There are are even other .cif files that have x-ray structure factors, NMR measurements, integrated hybrid models. It is unfortunate they decided to use the same file suffix for all these files and not even require file type information in the file.

[Greg Couch]

This is a limitation. Added a warning saying small-molecule CIF files are not supported if mmCIF reader doesn't return any structures.
