Zhao, Chongjian published the artcileSyntheses, structures and photoluminescence of Cd(II) coordination polymers based on in situ synthesized bifunctional ligands, Name: Pyridine-3-sulfonic acid, the publication is Inorganic Chemistry Communications (2014), 30-35, database is CAplus.
By employing Cd(II) salt, NaN3, and CN-(CH2)n-NC (n = 1, 2) and with the absence or presence of secondary ligands, four new cadmium coordination frameworks, named, {[Cd4(btm)4(H2O)2]·3H2O}n (1); [Cd2(btm)2(H2O)]n (2); [Cd2(bte)(PMA)0.5(H2O)]n (3); and [Cd(tzp)(2,2′-bipy)]n (4) (H2btm = bis(tetrazole) methane: H2bte = 1,2-bis(tetrazole-5-yl)ethane; H2tzp = 1H-tetrazolate-5-propionic acid; bipy = bipyridine; PMA = 1,2,4,5-benzenetetracarboxylic acid) were synthesized via in situ hydrothermal reaction. Single crystal x-ray diffraction reveals that compounds 1–3 are all three-dimensional (3D) frameworks. Compound 1 is constructed by Cd1- and Cd3-btm2- layers and large bridging metalloligands. Compound 2 exhibits a 3D framework with two-dimensional (2D) Cd-btm2- (adopting μ6:κN1, N1′: κN2: κN3: κN4: κN3′: κN4’coordination mode) layers pillared by μ3:κN1, N1′: κN2: κN4′ btm2-. Compound 3 is built up by the Cd-bte2- layers and the linker PMA, with left- and right-handed helical chains arranged alternately. It is notable that btm2- takes on six different coordination modes in 1 and 2. Compound 4 represents a 2D layered framework, which can be simplified into a Shubnikov plane net (4.82̂) topol. network with 3-connected T shape linker tzp2- ligands. In addition, the research results show that compounds 1–4 exhibit different fluorescent behaviors and thermal stabilities.
