Hello. If you have a powder difraction data, it is possile to search in powder database like PowCOD (http://www.ba.ic.cnr.it/softwareic/qualx/powcod-download/) using Qualx2 software (http://www.ba.ic.cnr.it/softwareic/qualx/). This program and the database is free for academy.

Too you can found articles related to this PCN-222 MOF with a CCDC number, and search this code in the CCDC dataase(https://www.ccdc.cam.ac.uk/structures/?). Best wishes,
