Magnetic and luminescence properties of Cu(II), Cu(II)4O4 core, and Cd(II) mixed-ligand metal–organic frameworks constructed from 1,2-bis(1,2,4-triazol-4-yl)ethane and benzene-1,3,5-tricarboxylate

A Cadmium Anionic 1-D Coordination Polymer {[Cd(H2O)6][Cd2(atr)2(μ2-btc)2(H2O)4] 2H2O}n within a 3-D Supramolecular Charge-Assisted Hydrogen-Bonded and π-Stacking Network

“…Coordination polymers based on mixed-linkers allow for a fine-tuning of MOF properties and can show additional characteristics such as crystal-to-crystal transformations [19], short and long-range magnetic ordering [20], luminescence [21], etc. [22].…”

“…The combination of neutral nitrogen donor ligands with anionic carboxylate ligands are frequent choices for the synthesis of mixed-ligand networks [22]. The linker 1,2-bis(1,2,4-triazol-4-yl)ethane (abbreviated as btre, Scheme 1) has recently been intensely studied in mixed-linker MOFs [19][20][21][22][23][24] and single-linker networks [25]. Herein, we report an attempt to construct a mixed-linker network with the 4,4 1 -bis(1,2,4-triazol-4-yl) (btr) ligand which was not hydrothermally stable under the synthesis conditions of 125˝C in water, so that the hydrolysis product 4-amino-1,2,4-triazole (atr) was incorporated instead (Scheme 1).…”

Synthesis, crystal structures and supramolecular architectures of square pyramidal Cu(II) complexes containing aromatic chelating N,N’-donor ligands

“…The coordination geometry of the copper(II) complexes depends on on the ligands, coligands, and counter ions [25][26][27][28][29][30][31][32][33][34][35][36][37][38]. Numerous Cu in different coordination environments have been developed to study the supramolecular Cu networks [39][40][41][42]. The five coordinated copper(II) complexes which containing N,N' chelating ligands and monodentate co-ligands have diverse stereo and physicochemical properties [25][26][27][28][29][30][31][32][33][34][35][36][37].…”

Construction of six coordination networks based on a flexible bis(methylbenzimidazole) ligand and isomeric benzenedicarboxylates

“…In our previous works, we have reported lots of fascinating structures based on semirigid N-donor ligand 1,4-bis-(2-methylbenzimidazol-1-ylmethyl)benzene [30,31] and 4,4 0 -bis(1,2,4-triazol-1-ylmethyl)biphenyl [32,33]. When spacers like methylene groups are introduced between the two 2-methylbenzimidazole rings instead of benzene ring, the resulting ligand acquires more flexibility [34]. On the basis of above mentioned, we designed a ligand 1,1 0 -(1,3-propane)bis-(2-methylbenzimidazole) (pbmb) (Chart 1) as a functional ligand.…”

“…Carboxylates acting as coligands have been extensively adopted to construct new complexes [37][38][39][40][41][42][43]. The phenyl dicarboxylate isomers containing two carboxyl groups at distinct positions can engender significant spatial effect and influence the structural assembly with multiform coordination fashions.…”
