“…The first metal coordination compound containing the 3,2′:6′,3″-terpyridine (3,2′:6′,3″-tpy) domain was reported in 2008 by Grafino et al and demonstrated metal binding by the outer pyridine rings of 4′-phenyl-3,2′:6′,3″-terpyridine ( 1 , Scheme 1 ) in the discrete molecular complex [Zn 2 (μ- 1 )(acac) 4 ]·H 2 O (Hacac = pentane-2,4-dione) [ 1 ]. This ditopic coordination environment is typical of 3,2′:6′,3″-tpy, although coordination through a single pyridine ring has also been observed, often when a coordinatively non-innocent functionality such as a carboxylate has been introduced into the 3,2′:6′,3″-tpy unit [ 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 ] or when protonation of a pyridine ring occurs [ 12 , 13 ]. Compared to 4,2′:6′,4”-tpy ( Scheme 1 ), 3,2′:6′,3″-tpy is conformational flexible ( Scheme 2 ), allowing the metal-binding domain to adapt to different environments imposed either by the coordination geometry of a metal center or to spatial constraints within the crystal lattice.…”

A Tail Does Not Always Make a Difference: Assembly of cds Nets from Co(NCS)2 and 1,4-bis(n-Alkyloxy)-2,5-bis(3,2′:6′,3″-terpyridin-4′-yl)benzene Ligands

The consistent assembly of a (65.8) cds net is observed in reactions of cobalt(II) thiocyanate with 1,4-bis(n-alkyloxy)-2,5-bis(3,2′:6′,3″-terpyridin-4′-yl)benzene ligands in which the n-alkyloxy substituents are n-propyl (ligand 3), n-butyl (4), n-pentyl (5), n-hexyl (6), n-heptyl (7), and n-octyl (8). Crystals were grown by layering a methanol solution of Co(NCS)2 over a 1,2-dichlorobenzene solution of each ligand. The choice of crystallization solvents is critical in directing the assembly of the cds net. Single-crystal structures of [Co(NCS)2(3)]n.3.5nC6H4Cl2, [Co(NCS)2(4)]n.5.5nC6H4Cl2, [Co(NCS)2(5)]n.4nC6H4Cl2, [Co(NCS)2(6)]n.3.8nC6H4Cl2, [Co(NCS)2(7)]n.3.1nC6H4Cl2, and [Co(NCS)2(8)]n.1.6nC6H4Cl2.2nMeOH (C6H4Cl2 = 1,2-dichlorobenzene) are presented and compared. The n-alkyloxy chains exhibit close to extended conformations and are accommodated in cavities in the lattice without perturbation of the coordination framework.

“…Because of excellent fluorescence performance of the Cd-nanosheet, we also explored its sensing ability as a fluorescent probe for organic small-molecular solvents. − Using the same research method, the Cd-nanosheet (3 mg) was soaked in 3 mL of different organic small molecular solvents (EtOH, DMF, dimethylacetamide, NMP, CH 2 Cl 2 , CHCl 3 , THF, CH 3 CN, acetone, toluene, dimethyl sulfoxide, pyridine, and nitrobenzene). After standing them for 24 h at room temperature, the Cd-nanosheet was fully dispersed in organic solvents by ultrasonication for 30 min, and finally, the luminescence was measured.…”

A cadmium(II) coordination polymer nanosheet (Cd-nanosheet) has been successfully constructed by a liquid–liquid interface-assisted method based on the coordination reaction between 1,3,5-tri(4-(2,2’:6′,2″-terpyridyl)phenyl)benzene and cadmium(II) nitrate. The Cd-nanosheet was characterized by elemental analysis, FT-IR spectroscopy, XPS, and fluorescence spectroscopy. The expected 2D lamellar structure was also confirmed by various microscopic techniques. The Cd-nanosheet is insoluble in aqueous and organic solvents. Due to its excellent fluorescence performance, we focus on its application in the detection of organic small molecules and metal ions. The luminescence quenching constant Ksv of the Cd-nanosheet for Cu2+ ions and nitrobenzene is 4.73 × 104 and 2.582 × 103 M–1, respectively. The results demonstrate that Cd-nanosheets can serve as detection sensors with high selectivity and sensitivity to detect nitrobenzene and Cu2+ ions.

In metal coordination compounds of the divergent ligands 4,2':6',4"‐terpyridine and 3,2':6',3"‐terpyridine and their 4'‐functionalized derivatives, the central pyridine ring of the 4,2':6',4"‐terpyridine and 3,2':6',3"‐terpyridine domains is non‐coordinated. We present an overview of data from the Cambridge Structural Database to assess whether there are structural similarities between the coordination compounds of 4,2':6',4"‐tpy and 1,3‐di(pyridin‐4‐yl)benzene, and between 3,2':6',3"‐tpy and 1,3‐di(pyridin‐3‐yl)benzene. Based upon structurally characterized compounds, it emerges that the coordination chemistry of ligands including one or more 4,2':6',4"‐terpyridine or 3,2':6',3"‐terpyridine metal‐binding domains dominate over those of corresponding ligands based upon 1,3‐di(pyridin‐4‐yl)benzene and 1,3‐di(pyridin‐3‐yl)benzene. We provide an overview of metallamacrocycles and cages, 1D‐coordination polymers and 2D‐ and 3D‐networks
