The crystal structures of the two compounds were solved by single-crystal X-ray diffraction methods. Both compounds show a 3-dimensional supramolecular structure directed by various interactions between tetrahalidometallate anions (ZnCl42-, CdI42-), water molecule and organic cations (H2CHBMA)2+. For both compounds, the cyclohexane ring of the template cation is in a chair conformation with the methylammonium substituent in the equatorial positions and the two terminal ammonium groups in a cis conformation but with two different orientations (upward for CP1 and downward for CP2) which influences the supramolecular architecture of the two structures. Hirshfeld surface analysis and the associated two-dimensional finger print plots were used to explore and quantify the intermolecular interactions in the crystals.2021http://zaguan.unizar.es/record/10220310.1007/s10854-021-05747-3http://zaguan.unizar.es/record/102203oai:zaguan.unizar.es:102203Journal of Materials Science: Materials in Electronics 32 (2021), 10890–10905byhttp://creativecommons.org/licenses/by/3.0/es/info:eu-repo/semantics/openAccess
