N,N′-[(2,3,5,6-Tetrafluoro-1,4-phenylene)dimethylene]bis(pyridine-3-carboxamide)

“…For general background, see: Chen, Yin et al (2007), ; Fujita (1998); Hagrman et al (1999); He et al (2006); Leininger et al (2000); Withersby et al (1999).…”

“…the length and the steric interaction) is crucial to the final observed coordination frameworks (Withersby et al, 1999). In efforts to systematically investigate the syntheses, molecular structures and coordination chemistry of such compounds, we have previously reported on N, N′-[(2,3,5,6-tetrafluoro-1,4-phenylene)-dimethylene] -bis(pyridine-2-carboxamide) (Chen, Yin et al, 2007), N,N′-[(2,3,5,6-tetrafluoro-1,4-phenylene)-dimethylene]-bis(pyridine-4 -carboxamide) (tfpbbp) (He et al, 2006) . In this contribution, we report the crystal structure (I).…”

“…Compound (I) was prepared according to the reported procedure of He et al (2006). Single crystals suitable for X-ray diffraction were obtained by slow evaporation of a methanol (10 mL) solution of (I) (0.03 g).…”

A self-assembled porous Zn(II) metal–organic framework based on fluorinated bis-pyridinecarboxamide derivative ligand: Synthesis, structure and properties

“…On the other hand, owing to the weak intermolecular forces among fluorinated compounds [16], much of the recent research has focused on the construction of fascinating coordination networks by the use of fluorinated ligands containing a rigid or flexible backbone, such as 1,4-bis(4-pyridyl)-2,3,5,6-tetrafluorobenzene and 1,4-bis(4-pyridylmethyl)-2,3,5,6-tetrafluorobenzene [17]. In order to explore the intriguing chemistry of MOFs with unique properties, we have embarked on the synthesis of a new fluorinated ligand, N, N 0 -[(2,3,5,6-tetrafluoro-1,4-phenylene)bis(methylene)]bis (pyridine-4-carboxamide) (tfpbbp) (Scheme 1) [18] and thus achieved a novel 1-D metal-organic polymer [Zn-(tfpbbp)(Ac) 2 ] n (1). Herein, we report the synthesis, structure, thermal and solid-state photoluminescent properties of (1).…”
