Synthesis, crystal structure and photoluminescent property of a novel indium (III) supramolecular 3D framework

Two novel indium coordination polymers derived from 2,6-pyridinedicarboxylate ligand: Syntheses, structures and photoluminescent properties

“…Cl(1) and Cl (2) atoms occupy the axial vertexes of pentagonal bipyramid with Cl(1)-In(1)-Cl(2) angle being 173.50(3)°, significantly deflected Table 1 Crystal data and structure refinements for 1 and 2. from the ideal value of 180°. All of In-O and In-N distances are similar to those reported for other indium oxygen and indiumnitrogen donor compounds [18,19]. For In(2) ion, it adopts sixcoordination geometry to construct a slightly distorted octahedron by two oxygen atoms, two nitrogen atoms and two chlorine atoms with the bond lengths being 2.1574(14), 2.3515(16) and 2.4289(9) Å for In-O, In-N and In-Cl, respectively ( Fig.…”

“…The emission band for the free 2,6-H 2 pdc ligand is at 375 nm excited at 330 nm and that of the free bipy ligand is at 420 and shoulder bands at 443 and 459 nm excited 340 nm ( Fig. S4), which can be owing to the p * -p transition [17][18][19]. As shown in Fig.…”

“…A 1.5 (C 3 N 2 H 3 )(C 3 N 2 H 4 ) 0.5 ]ÁDMFÁ(CH 3 CN) 0.5 is proved to be a potential candidate for hydrogen storage material [15] and three unique cage-within-cage-based porous materials exhibit high photochemical stability and high CO 2 uptake capacity [16]. In addition, as the d 10 metal ions, In(III)-CPs also display intense photoluminescent emissions [17][18][19]. Therefore, the study on In(III)-CPs may cast some light on the design and synthesis of functional CPs.…”

Indium-Based Metal–Organic Framework for Efficient Photocatalytic Hydrogen Evolution

“…Herein, we designed and successfully constructed a novel indium­(III)-based MOF (In-MOF). In III was selected as the metal node based on the following considerations. − (1) In III as a low-toxicity p-block metal can change its valence to produce diverse structures with unique coordination and chemical characteristics. (2) In III as a functional metal center can be used as a Lewis acid catalyst.…”
