Synthesis, characterization and luminescence of Cd(II), Zn(II) complexes with 1,2,3-triazole derivatives and in situ solvothermal decarboxylation of the ligands

Construction of Zn(II)/Cd(II) coordination polymers derived from a tetrazole derivative: Syntheses, structures and luminescent properties

“…As depicted in Figure 1, each Zn(II) ion is five-coordinated by three nitrogen atoms from two symmetrically related Htip -ligands, one water oxygen atom and one Cl atom to form a slightly distorted tetragonal pyramid coordination geometry. The Zn-N bond lengths (Table S1) range from 2.025 to 2.222 Å, which are similar to those reported in the literature [22]. In 1, the terminal tetrazole group of Htip -ligand is slightly twisted with respect to the phenyl ring to relieve the steric hindrance, and the dihedral angle between them is 33.561°.…”
