“…Noticeably, rigid rod-type ligands such as bipyridine (bpy), terephthalic acid or their analogues, often employ as linear pillars to construct entangled CPs [17,18]. Besides the rigid ligands, the flexible ligands including flexible N-donor (4-pyridyl)ethane (bpe), (4-pyridyl)propane (bpp), 1,2-bis(4-pyridyl)ethylene (bpee), and O-donor 1,4-phenylenediacetic acid (H 2 pphda) and 1,2-phenylenediacetic acid (H 2 ophda) have different shapes associated with the trans Crystals 2019, 9, or gauche conformation, favoring the formation of interesting topologies [19][20][21][22]. In our previous study, we have synthesized a rigid multi-N-donor 1,4-di(1H-imidazol-4-yl)benzene (L) ligand and employed to build porous coordination polymer with favorable gas adsorption properties [23].…”

Two Zn(II) coordination polymers (CPs) [Zn(L)(pphda)] (1) and [Zn(L)(ophda)]·H2O (2) were prepared by reactions of ZnSO4·7H2O based on the N-donor 1,4-di(1H-imidazol-4-yl)benzene (L) ligand and two flexible carboxylic acids isomers of 1,4-phenylenediacetic acid (H2pphda) and 1,2-phenylenediacetic acid (H2ophda) as mixed ligands, respectively. Structures of CPs 1 and 2 were characterized by elemental analysis, Infrared spectroscopy (IR), thermogravimetric analysis and single-crystal X-ray diffraction. The CP 1 is a fourfold interpenetrating 66-diamond (dia) architecture, while 2 is a 2D (4, 4) square lattice (sql) layer based on the Zn2(cis-1,2-ophda2−)2 binuclear Zn(II) subunits. The luminescent property, including luminescence lifetime and quantum yield (QY), have been investigated for CPs 1 and 2.

“…Generally, two important kinds of ligands, including N-donor and O-donor organic compounds, are widely used to construct diverse CPs, due to their various coordination modes and modifiable backbones [16,17]. Noticeably, rigid rod-type ligands, including 4,4 -bipyridine (bpy), terephthalic acid, or their analogues, often act as pillars in building a rich variety of new entangled CPs [18,19], while the flexible ligands have different shapes associated with the trans or gauche conformation, favoring the formation of interesting entanglements [20,21]. More recently, a new type of rigid N-donor ligand, including the 4-imidazolyl group, has been designed by our group, and employed to fabricate porous crystalline materials with good gas adsorption properties [22][23][24][25][26][27][28][29][30][31][32][33][34].…”

Two interpenetrated coordination polymers (CPs) {[Zn1(L)(NO2pbda)]n[Zn2(L)(NO2pbda)]n} (1) and [Zn(L)(Brpbda)]n (2) were prepared by reactions of zinc sulfate heptahydrate with N-donor ligands of 1,4-di(1H-imidazol-4-yl)benzene (L) and auxiliary carboxylic acids of nitroterephthalic acid (H2NO2pbda) and 2,5-dibromoterephthalic acid (H2Brpbda), respectively. The structures of the CPs were characterized by Fourier-Transform Infrared (IR) spectroscopy, elemental analysis, and single-crystal X-ray diffraction. The coordination polymer 1 has two different (4, 4) sql 2D layer structures based on the [Zn(L)(NO2pbda)] moiety, which results in inclined interpenetration with a 2D + 2D → 3D architecture, while the CP 2 exhibits a 3-fold interpenetrating dmp network. The diffuse reflectance spectra are also investigated for the CPs 1 and 2.

2016) Construction of three new metal-organic frameworks with distinct SBUs: trinuclear {Cd 3 (COO) 6 } clusters, inorganic -Cd-O-Cd-chains, and heterometallic trinuclear {Cd 2 Key laboratory of Coal to ethylene Glycol and its related technology, fujian institute of research on the structure of matter, Chinese academy of sciences, fuzhou, Pr China ABSTRACT Three metal-organic frameworks (MOFs), [Cd 3 (OABDC) 2 (e-urea) 4 ] n (1), [Cd 3 (OABDC) 2 (H 2 O) 5 )] n ( 2) and [Cd 2 Ba(OABDC) 2 (H 2 O) 7 ] n (3) (H 3 OABDC = 5-oxyacetate isophthalic acid, e-urea = 2-imidazolidinone), were prepared using H 3 OABDC and metal salts. Single-crystal X-ray diffraction analyses reveal that 1 features a 2-D layered structure constructed from trinuclear {Cd 3 (COO) 6 } SBUs and represents a (3,6)-connected kgd topology. Compounds 2 and 3 are 3-D inorganic-organic hybrid frameworks; 2 employs infinite inorganic -Cd-O-Cd-chains as SBUs, whereas (3,6)-connected anttype 3 employs heterometallic trinuclear {Cd 2 Ba(COO) 4 } clusters as SBUs. The structures of these three compounds indicate that the SBUs play an important role in the construction of MOFs. Moreover, the thermal stabilities and solid-state photoluminescent properties of these three compounds have also been investigated.
