Template synthesis, structure and electrochemistry of trinuclear iron(II) clathrochelate dioximates with ferrocenylboron fragments

Preparation and characterization of novel [Fe(methylisopropylglyoximato)2(amine)2] mixed chelates

“…Voloshin et al synthesized a series of iron complexes and analyzed them using IR, NMR, Mössbauer and X-ray diffractometry [14][15][16]. They investigated the electrochemical response of hydrogen peroxide oxidation on gold electrode modified with [FeBd 2 (GlyoxHSCH 2 CH 2-SH)(BF) 2 ] (BdH 2 = benzyldioxime and GlyoxH 2 = glyoxime) clathrochelate self-assembled monolayer and found to be very precise and sensitive in amperometric determination of H 2 O 2 [17].…”

How Good is Clathrochelate Framework in Facilitating Long-Range Electron-Transfer? Case Study of the Ferrocenylboron-Capped Iron(II) Clathrochelate

“…[11] The earlier-described electrochemical studies of FeDm 3 (BFc) 2 complex are not suitable for careful evaluation of such metal-metal coupling because these experiments have been performed using (Bu 4 N)(BF 4 ) as an electrolyte that is known to possess a relatively strong ion-pairing ability. [4] In this work, we used DCM/0.05M TFAB system for the electrochemical studies in order to suppress an ion-pairing effect. The measured cyclic voltammetry (CV) and differential pulse voltammetry (DPV) data for FeDm 3 (BFc) 2 complex are shown in Figure 1.…”

“…The FeDm 3 (BFc) 2 complex was prepared and purified as described elsewhere. [4] Instrumentation. All UV-Vis data were obtained on a Jasco V-670 spectrophotometer at room temperature.…”

New o-carboranyl-containing capping agents for d-metal tris-dioximates and first bis-C-carboranylboron-capped iron(II) clathrochelates: Synthesis and X-ray structure

“…TP-TAP distortion u angle of the coordination polyhedron of the encapsulated iron(II) ion is equal to 20.4°. This value is also characteristic of the boroncapped tris-nioximate iron(II) complexes [20]: several structures of these complexes were obtained by X-ray crystallography (FeNx 3 (BFc) 2 Á 2CCl 4 [30], FeNx 3 (Bn-C 4 H 9 ) 2 [31], FeNx 3 (BCH 2 -CH@CH 2 ) 2 [32], FeNx 3 (Bn-C 16 H 33 ) 2 [32], FeNx 3 (BC 6 H 3 (OCH 3 ) 2 ) 2 Á CHCl 3 [33], FeNx 3 (BC"C-C 6 H 5 ) 2 Á C 6 H 5 CH 3 [33] and FeNx 3 (BAd) 2 Á C 6 H 12 [16]). TP-TAP distortion u angles for these compounds vary in a wide range from 9.5°to 22.9°and the u angle value for 5b is inside of this range.…”

“…In this paper, we report the first use of C-carboranylboronic acid derivatives for capping of the clathrochelate complexes with an encapsulated metal ion as well as the first X-ray structure of the clathrochelate tris-dioximate with two apical carboranyl substituents. The complexes of alicyclic cyclohexanedion-1,2-dioxime (nioxime) are more stable and much easy to form than the similar acyclic compounds [18].…”
