“…The organometallic chemistry of dibismuth compounds has been largely developed by Breunig et al and a variety of structures exist whereby dibismuthenes and -ynes coordinate transition metal fragments [124,125]. The inactivity of the bismuth lone pair in such species means that the metals are largely coordinated by the electrons in the double or triple Bi-Bi bond.…”

“…Organoantimony compounds have been synthesized and used in organic reaction as well as in the fields of catalysis, biochemistry and medicine [16][17][18][19][20][21][22][23][24][25][26]. Most of the applications are focused on in vitro antitumour activity and organic reactivity [21][22][23][24].…”

Scientific interest in coordination and organome tallic antimony(V) derivatives is continuously increas ing in the recent two decades [1][2][3][4], which is due to the possibility of using these compounds in diverse areas of fundamental and applied science. These com plexes demonstrate structural variety from monomeric compounds to associated structures and supramolecu lar ensembles [5][6][7][8][9][10]. The antimony compounds are used as components of catalytic systems and reagents in fine organic and organometallic synthesis [11][12][13][14]. In addition, many organoantimony compounds dem onstrate antimicrobial properties and possess antitu mor activity [15][16][17].The chemistry of coordination compounds of o quinone and related ligands is widely developed to the present time [18][19][20] because of the use of their com plexes as model objects in magnetochemical studies, for the construction of molecular switchers, and as catalytic systems. Sterically hindered di o quinones are presently studied to a less extent, although they represent a promising type of ligands for the design of spatially ordered structures [21][22][23][24][25]. The introduction of various binding units (bridging groups) into the di o quinone structure makes it possible to change con siderably the character of mutual effects of the o quinone moieties in the di o quinone molecule and to vary the exchange magnetic interactions between the radical anion semiquinone derivatives from antiferro magnetic to ferromagnetic [22,24].In addition, the most part of studies of the o quinone complexes was carried out with the transi tion metal compounds, whereas the coordination chemistry of nontransition metals with redox active ligands is poorly studied [26]. This is also valid for the antimony o quinone complexes. Among the binuclear antimony complexes (bis(catecholate) derivatives), the derivatives of 4,4' di [(3 methyl 6 tert butyl o benzoquinone) and di o quinones based on 3,6 di tert butyl o benzoquinone containing the ethylene or piperazine bridging groups were described [27][28][29][30].The purpose of the present work is to synthesize antimony(V) bis(catecholate) complexes based on nonsymmetric 1,1' spirobis[3,3 dimethylindane quinone 5,6] (Q Spiro Q) and to study them by IR and NMR spectroscopy and cyclic voltammetry (CV). EXPERIMENTALThe synthesis and study of the properties of the complexes were carried out in evacuated ampules in the absence of oxygen. In all cases, the yields of the target products were higher than 90%. The solvents Triaryl and Trialkylantimony(V) Bis(catecholates) Based on 1,1' Spirobis[3,3 Dimethylindanequinone 5,6]: Abstract-A series of new binuclear bis(catecholate) antimony(V) complexes based on 1,1' spirobis[3,3 dimethylindanequinone 5,6] with various substituents at the central antimony atoms, R 3 Sb(Cat Spiro Cat)SbR 3 (I-IV) and R 3 Sb(Cat Br Spiro Br Cat)SbR 3 (V-VIII) (R = p fluorophenyl, phenyl, p tolyl, and ethyl), were synthesized.
