a, Relations between tetrahedra organization in zeolites and STs organization in ZMOFs. Schematic presentation of two possible ways to deviate from default mtn topology 5MR. b, Tightening apexes of neighbouring STs with polytopic cSDA decreasing TOT angle from 180° default for mtn topology to 160° for sod topology forming 4MR. c, Expanding two apexes of neighbouring STs with polytopic cSDA to form 6MR preventing 5MR formation.
