Synthesis, crystal structure, luminescence and thermal behavior of a new energetic zinc(II) compound

Syntheses, crystal structures and thermal decomposition studies of two novel Mn(ii)-MOFs with tetrazole-based carboxylic acids

“…In our previous work, a series of tetrazole-based carboxylic acids such as N -(1-carboxymethyltetrazole-5-yl)- N -(2′-carboxymethyltetrazole-5′-yl)amine, 11,12 1,3-bis(2-carboxymethyltetrazol-5-yl)benzene (H 2 L 1 ), 13–15 1,4-bis(2-carboxymethyltetrazol-5-yl)benzene, 16 1,3,5-tri(2-carboxymethyltetrazol-5-yl)benzene, 2,14,17–19 and 2-(5-(3-pyridyl)tetrazol-2-yl)propionic acid (HL 2 ) 20–24 have been designed and successfully prepared. Their MOFs with Mg( ii ), Ca( ii ), Sr( ii ), Ba( ii ), Pb( ii ), Mn( ii ), Co( ii ), Zn( ii ), and Cd( ii ) ions have been synthesized and the related properties like luminescence, 2,11,16 thermal decomposition, 13,16,17,20,21,24 proton conduction 2 and anticancer activity 22,23,25 have also been researched. As a continuation of our investigation on the tetrazole-based carboxylic acids, herein we present two new Mn( ii )-MOFs: [Mn(L 1 )(DMF)(H 2 O)]·0.375H 2 O ( 1 ) and [Mn(L 2 ) 2 ] ( 2 ) derived from H 2 L 1 and HL 2 ligands (Scheme 1).…”

Nitrogen-Rich Energetic Metal-Organic Framework: Synthesis, Structure, Properties, and Thermal Behaviors of Pb(II) Complex Based on N,N-Bis(1H-tetrazole-5-yl)-Amine

“…Many investigators have recently demonstrated the possibility of using nitrogen-rich MOFs as high explosives [25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48]. MOFs consist of metal ions (Pb 2+ , Ag + , etc.…”

“…In the past decade, metal-organic frameworks (MOFs) have elicited much interest in chemistry, material science, medicine, and environmental science [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 ] because of their stable architectures, controllable structures, modifiable properties, and potential applications in gas storage [ 10 , 11 , 12 , 13 ], chemical separation [ 14 , 15 , 16 , 17 ], catalysis [ 18 , 19 , 20 , 21 ], chemical sensor technology [ 5 ], drug delivery [ 22 , 23 , 24 ], and so on. Many investigators have recently demonstrated the possibility of using nitrogen-rich MOFs as high explosives [ 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 ]. MOFs consist of metal ions (Pb 2+ , Ag + , etc.…”

“…Fifth, the azide group hidden in aminotetrazole is the best stable moiety by virtue of the extended 6 π system. Therefore, many MOFs based on H 2 bta, such as Cu(II) [ 39 , 62 , 63 , 64 ], Co(II,III) [ 36 , 50 ], Fe(III) [ 65 ], Mn(II) [ 66 , 67 ], Zn(II) [ 46 , 66 , 68 , 69 ], Cd(II) [ 66 ] MOFs, and others [ 70 ], have been obtained and investigated.…”
