One‐Dimensional Looped Chain and Two‐Dimensional Square Grid Coordination Polymers: Encapsulation of Bis(1,2,4‐Triazole)‐trans‐cyclohexane into the Voids

Abstract

Two new coordination polymers [Cu(btzx)2(MeOH)2](NO3)2 (1) and [Cu(btrcy)2(H2O)2](ClO4)2·btrcy (2) have been synthesized by reacting two bis‐triazole/tetrazole‐ligands namely m‐xylylene‐bis(tetrazole) (btzx) and bis(1,2,4‐triazole)‐trans‐cyclohexane (btrcy) with Cu(NO3)2 and Cu(ClO4)2 respectively in a 1:3 metal/ligand ratio. These compounds are shown to form X‐ray quality single‐crystals under different conditions, and the crystal structures have been determined by single‐crystal X‐ray diffraction (SXRD). The SXRD data analysis revealed that 1 and 2 are 1D looped chain and 2D‐square grid coordination polymers, respectively. More interestingly, the 2D‐square grid architecture in 2 acts as an excellent host for the large guest ligand molecule btrcy, which is encapsulated within the voids of the 2D coordination polymer.
