Kumar, Deepak published the artcileSyntheses and characterizations of calcium and strontium based coordination compounds with the 5-(2-pyridyl)tetrazolate ligand, respectively exhibiting extended 1 D and 2 D structures, SDS of cas: 100-70-9, the main research area is calcium strontium pyridyltetrazolate complex preparation crystal structure luminescence; thermal stability calcium strontium pyridyltetrazolate complex.
Coordination compounds of calcium and strontium with 5-(2-pyridyl)tetrazolate ligand (2-PTZ) were obtained by the reactions of the resp. metal nitrates with 2-cyanopyridine, 2-cyanoacetamide and sodium azide in aqueous solutions Both the complexes have similar composition i.e. [M(2-PTZ)2(H2O)4]n.2nH2O where M = Ca(II) (1) and Sr(II) (2). The products were characterized by FTIR spectra and single-crystal x-ray diffractions. Their photoluminescences, bandgaps, and thermal properties were studied. Single crystal x-ray diffractions revealed that both 1 and 2 have distorted square anti-prismatic mol. geometries wherein the two 2-PTZ anions act as bidentate ligands by coordinating via their pyridine-N and tetrazole-N atoms. In both the mols. six water mols., of which four acting as monodentate ligands, and the remaining two in the lattices were present. The lattice H2O mols. significantly stabilized the structures through N··H··O hydrogen bonds with the 2-PTZ ligands in the structures. Compound 2 (with around 50% decomposition) shows better thermal stability than calcium-based compound 1(72% decomposition).
