Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, ChemPlusChem called Two Six-Connected MOFs with Distinct Architecture: Synthesis, Structure, Adsorption, and Magnetic Properties, Author is Ren, Guo-Jian; Han, Song-De; Liu, Yan-Qing; Hu, Tong-Liang; Bu, Xian-He, which mentions a compound: 14389-12-9, SMILESS is C1(C2=NN=NN2)=CC=NC=C1, Molecular C6H5N5, Computed Properties of C6H5N5.
By assembling CoII ions and a combination of 5-(4-pyridyl)tetrazole (4-ptz) and formate ions, two distinct metal-organic frameworks, [Co3(4-ptz)5(HCOO)(H2O)2] and [Co3(4-ptz)4(DMF)2(HCOO)2] (DMF=N,N’-dimethylformamide), were synthesized. They were both characterized by single-crystal x-ray diffraction, IR spectroscopy, TGA, and powder X-ray diffraction. Structural analyses revealed that by slightly modulating the coordination environment of the trinuclear cobalt cluster, two complexes were formed featuring unusual six-connected nets reminiscent of a pyrazole-type linear trinuclear cobalt cluster as compared with the classic eight-connected bcu topol. In addition, [Co3(4-ptz)5(HCOO)(H2O)2] interacted strongly with CO2, with an adsorption enthalpy of 29.2 kJ mol-1, and in a selectivity study, the uptake ratios of CO2/N2 (from a 15:85 mixture) and CO2/CH4 (50:50 mixture) were 77.6 and 37.7, resp. Magnetic studies on both complexes revealed weak antiferromagnetic coupling between the CoII ions.
