Synthesis and structure of silver copper salts complexes with polyhedral boron hydride anions, including closo-decaborate [B10H10]2−, closo-dodecaborate [B12H12]2−, 1-carba-closo- decaborate [1-CB9H10]−, carba-closo-dodecaborate [CB11H12]−, cobalt bis(dicarbollide) [3,3′-Co(1,2-C2B9H11)2]− anions their derivatives, are reviewed. The demonstrate a wide variety structural types, relating to both the metal coordination environment modes anions. latter can range from strong via polyhedron...
This review systematizes data on the coordination ability of mono- and disubstituted derivatives boron cluster anions carboranes in complexation with transition metals. Boron clusters [BnHn]2–, monocarborane [CBnHn–1]–, dicarboranes [C2BnHn–2] (with non-functionalized carbon atoms) (n = 10, 12) containing B–X exo-polyhedral bonds (X N, O, S, Hal) are discussed. Synthesis structural features complexes known to date described. The effect complexing metal substituent attached cage composition...
In the course of study, nanocrystalline cobalt monoboride was prepared by thermal decomposition precursors [Co(DMF)6][An], where [An] = [B12H12]2- (1), [trans-B20H18]2- (2) or [B10Cl10]2- (3) in an argon atmosphere. Three new salt-like compounds 1-3 were when Co(NO3)2 allowed to react with (Et3NH)2[An]. Compound 1 is new; structures 2 and 3 have been previously reported. Samples annealed at 900 °C form samples 1a-3a, which characterized single crystal XRD for powder 1-3. Powder on products...
Interaction of [Cu2B10H10] with 2,2'-bipyridine (bipy) afforded a novel binuclear discrete complex the [Cu2(bipy)2B10H10] composition. Two copper(I) atoms coordinate bridge boron cage through an apical edge and triangular BBB face situated at its opposite vertices to form four 3c2e (CuHB) one 2c2e Cu-B bonds. The charge density model was obtained by functional theory calculations isolated molecule crystal. resultant densities were analyzed using quantum in molecules (QTAIM) electron...
Abstract A series of salts and complexes containing trans ‐ iso ‐isomers octadecahydro‐eicosaborate [B 20 H 18 ] 2− dianion is synthesized characterized using FTIR 11 B NMR spectroscopies X‐ray diffraction techniques. Both isomers are found to act as four‐, bi‐, or zero‐dentate ligands in reactions with copper(II), silver(I), lead(II) through apical and/or equatorial boron atoms. Solid‐state photo‐ thermoinitiated isomerization solvent cleavage occurring these compounds a...
Abstract Solvent-free copper(I) and thallium(I) compounds of the general formula [M 2 [B 10 H ]] have been synthesized. The identified by IR spectroscopy X-ray diffraction. According to diffraction data, structures both are three-dimensional frameworks. In complex [Cu n , formation three-center M–H–B bonds is observed. compound Tl ], bond between cations anions ionic, which confirmed data. Hirschfeld surface analysis boron cluster anion was performed for identify analyze intramolecular interactions.
For the first time, a systematic study of behavior Ag2[B12Cl12] in oxygen-containing organic solvents various nature (acetone, N,N-dimethylformamide (DMF), dimethoxyethane (DME), methanol (CH3OH), and tetrahydrofuran (THF)) was conducted. The used were found to compete with perchlorinated [B12Cl12]2– anion, forming silver(I) coordination polyhedron. A number compounds compositions structures solvent molecules acting as ligands obtained characterized by physicochemical methods. polymer...
