Coordination frameworks and metal‐organic frameworks built from simple triazole ligands such as 1 H ‐1,2,3‐triazole ( H‐ta ) have recently inspired great interest owing to physical phenomena such as electronic conductivity, phase transitions and their magnetic behavior. In line of our endeavors we report on the solvothermal reaction of MnCl 2 ⋅ 4H 2 O with H‐ta ligand in isopropyl alcohol leading to the the novel CFA‐23 (((propan‐2‐yl)oxidanium) + [Mn 6 Cl 5 (ta) 8 ] − ; CFA‐23=Coordination Framework Augsburg University‐23) coordination framework. Single‐crystal X‐ray diffraction (SC‐XRD) reveals that it crystallizes in the tetragonal space group P 4 2 /nnm (134) exhibiting a two‐fold interpenetrated framework with the topologies of a dia net with point (Schläfli) symbol 6 6 . The thermal stability of this compound was investigated using variable temperature X‐ray powder diffraction and thermogravimetric analysis. The magnetic properties of CFA‐23 differ from a similar non‐interpenetrated literature structure of the composition (H[Mn 6 (bta) 8 Cl 5 ] ⋅ (H 2 O) 4 ) built from 1 H ‐1,2,3‐benzotriazole, thus, indicating that sterically induced lattice changes might be an adjustment parameter for magnetic properties in such frameworks.
