A scorpion-like NHC Ag(I) complex based on triazinetrione: Preparation, structure and recognition to dihydrogen phosphate
A tri-imidazolium salt LH3·(PF6)3 and its NHC (N-heterocyclic carbene) Ag(I) complex 1 were prepared and characterized. The structures of LH3·(PF6)3 and 1 were demonstrated by X-ray diffraction analysis. In LH3·(PF6)3, two imidazoles lied on the same side of triazinetrione plane, and the third imidazole lied on another side of triazinetrione plane. Complex 1 was of a scorpion-like structure with a 12-membered macrometallocycle. Additionally, the selective recognition of 1 for H2PO4- was studied on the basis of fluorescent spectra, 1H NMR, MS and IR. The high association constant for 1·H2PO4- (K = 3.3 × 104 M-1) showed that 1 had strong association ability to H2PO4-. The low detection limit (2.54 × 10-10 mol/L) indicated that the detection of 1 to H2PO4- was sensitive.
期刊介绍：
The Journal of Organometallic Chemistry targets original papers dealing with theoretical aspects, structural chemistry, synthesis, physical and chemical properties (including reaction mechanisms), and practical applications of organometallic compounds.
Organometallic compounds are defined as compounds that contain metal - carbon bonds. The term metal includes all alkali and alkaline earth metals, all transition metals and the lanthanides and actinides in the Periodic Table. Metalloids including the elements in Group 13 and the heavier members of the Groups 14 - 16 are also included. The term chemistry includes syntheses, characterizations and reaction chemistry of all such compounds. Research reports based on use of organometallic complexes in bioorganometallic chemistry, medicine, material sciences, homogeneous catalysis and energy conversion are also welcome.
The scope of the journal has been enlarged to encompass important research on organometallic complexes in bioorganometallic chemistry and material sciences, and of heavier main group elements in organometallic chemistry. The journal also publishes review articles, short communications and notes.
