Researchers have introduced MOFjson, a novel representation for metal-organic frameworks (MOFs) designed to improve how language models understand their structure. Unlike previous formats that separate atomic geometry from topological information, MOFjson explicitly separates raw atomic data with bond shift vectors from derived layers detailing secondary building units and network topology. This new format has demonstrated superior performance across four different language models on a benchmark designed for MOFs, outperforming existing methods in tasks such as identifying periodic copies, characterizing crystal systems, and determining coordination numbers.
