The reaction of cis-[PdCl2(CNXyl)2] (Xyl = 2,6-Me2C6H3) with various 1,3-thiazol- and 1,3,4-thiadiazol-2-amines in chloroform gives a mixture two regioisomeric binuclear diaminocarbene complexes. For 1,3-thiazol-2-amines the isomeric ratio depends on conditions kinetically (KRs) or thermodynamically (TRs) controlled regioisomers were obtained at room temperature heating, respectively. In CHCl3 solutions, isomers are subject to reversible isomerization accompanied by cleavage Pd–N C–N bonds...
The nitrosoguanidinate complex [Ni{NH═C(NMe2)NN(O)}2] (1) was cocrystallized with I2 and sym-trifluorotriiodobenzene (FIB) to give associates 1·2I2 1·2FIB. Structures of these solid species were studied by XRD followed topological analysis the electron density distribution within framework Bader's approach (QTAIM) at M06/DZP-DKH level theory Hirshfeld surface analysis. Our results along inspection (CCDC) data, accompanied theoretical calculations, allowed identification three types Ni···I...
Three diaryliodonium tetrachloroaurates(III), [Ar1IAr2][AuCl4] (Ar1/Ar2 = Ph/Ph (1), Ph/Mes (2), o-(C6H4)2 (3)), were obtained as solids (62–80%) by the metathetical reaction of [Ar1IAr2](CF3CO2) and H[AuCl4]. In particular, single-crystal X-ray diffraction studies 1–3 revealed three-center bifurcated C–I···(Cl–Au–Cl) halogen bond (XB) more conventional interionic two-center C–I···Cl–Au XB. An XB with iodine(III) center a cation can be formed even when ∠(C–I···X) is much less than 180°...
The electrochemical behavior of [trans-RuCl4L(DMSO)]- (A) and [trans-RuCl4L2]- (B) [L = imidazole (Him), 1,2,4-triazole (Htrz), indazole (Hind)] complexes has been studied in DMF, DMSO, aqueous media by cyclic voltammetry controlled potential electrolysis. They exhibit one single-electron RuIII/RuII reduction involving, at a sufficiently long time scale, metal dechlorination on solvolysis, as well as, organic media, reversible RuIII/RuIV oxidation. redox values are interpreted the basis...
Metal-mediated reaction between equimolar amounts of cis-[MCl2(C≡NR)2] [M = Pd, R cyclohexyl (Cy) 1, tBu 2, 2,6-Me2C6H3 (Xyl) 3, 4-MeOC6H4 4; M Pt, 5, 7, 8] and benzophenone hydrazone, H2N−N═CPh2, proceeds in CHCl3 under reflux for 8 h. The subsequent workup provides the carbene species cis-[MCl2{C(N(H)N═CPh2)═N(H)R}(C≡NR)] (M 9−12; 13−15) good (80−85%) isolated yields. Complexes 9−15 are air- moisture-stable 20−80 °C temperature range were characterized by elemental analyses (C, H, N),...
The dihalomethane–halide H2C(X)–X···X– (X = Cl, Br) halogen bonding was detected in a series of the cis-[PdX(CNCy){C(NHCy)═NHC6H2Me2NH2}]X•CH2X2 associates by single-crystal XRD followed DFT calculations. Although ESP calculations demonstrated that σ-hole dichloromethane is smallest among all halomethane solvents (the maximum electrostatic potential only 2.6 kcal/mol), theoretical Bader's QTAIM analysis (M06/DZP-DKH level theory) confirmed bond both solid-state and gas-phase optimized...
In the current study, we evaluated solubility of a number organometallic species and showed that it is noticeably improved in diiodomethane when compared to other haloalkane solvents. The better solvation properties CH2 I2 were associated with substantially σ-hole-donating ability this solvent, which results formation uniquely strong solvent-(metal complex) halogen bonding. strength bonding attenuated by introduction additional atoms owing competitive more favourable intermolecular...
The current paper introduces the use of stable carbonyl containing ruthenium complexes, [Ru(bpy)(CO)<sub>2</sub>X<sub>2</sub>] (X = Cl, Br, I), as halogen bond acceptors for a I<sub>2</sub>halogen donor.
