A new heterometallic selenide-bridged 60-electron complex containing the cubane cluster fragment [M03(μ3-Se)4Pd]4τ was prepared by heating a solution of [Mo3Se4(H2O)9]Cl4 and palladium black in 2M HCl. The cluster complex was isolated from aqueous solutions as a hydrolytically stable supramolecular adduct with macrocyclic
cavitand cucurbituril. The molecular and crystal structure of {[ClPdMo3Se4(H2O)7Cl2](C36H36N24O12)Cl}·7H2O were established by X-ray diffraction analysis.

Supramolecular compounds {[Cr(H2O)6](C36H36N24O12)}(NO3)3 · 13H2O (I) and {[Ni(H2O)6]2(C36H36N24O12)}(SO4)2 · 16H2O (II) were obtained from aqueous solutions of chromium nitrate or nickel sulfate and the macrocyclic cavitand cucurbituril. According to X-ray diffraction analysis data, the cucurbituril molecule is closed from both sides by metal aqua complexes due to the formation of hydrogen bonding between the cucurbituril CO groups and aqua ligands. Compound I has a chain structure, while the structure of compound II is layered. Modes of cucurbituril coordination, depending on the size and charge of the metal cation, are discussed. 相似文献

Slow evaporation of hydrochloric acid solutions of zirconium(iv) or hafnium(iv) oxochlorides and cucurbituril in air afforded compounds with composition [M4(OH)8(H2O)16]Cl8·(C36H36N24O12)·16H2O, where M = Zr (1) or Hf (2). According to the X-ray diffraction data, complexes 1 and 2 are isostructural. Their crystal structures can be described as packings of polymer chains consisting of alternating cucurbituril molecules and tetranuclear cations [M4(OH)8(H2O)16]8+ linked to each other via an extensive network of hydrogen bonds. Compound 2 is the first structurally characterized tetranuclear hafnium aqua complex. 相似文献

The following adducts of cucurbit[6]uril and cucurbit[8]uril with triangular cluster chloroaquacomplexes have been prepared and characterized: {[Mo3S4(H2O)7Cl2]2(CB[6])}Cl4·13H2O (I), (H3O)2{[Mo3Se4×(H2O)6Cl3](CB[6])}Cl3·3.5H2O (II) and (H3O)2{[Mo3S4(H2O)4Cl5](CB[8])}Cl·14H2O (III). It is shown that the formation of complementary hydrogen bonds in the systems cucurbit[6]uril/[M3Q4(H2O)9?x Clx](4?x)+ (x = 1–3) results in a selective isolation of isomers containing chlorine atom in the trans-position to the capping μ3-ligand. For large x, a selective inclusion of one or another form into the supramolecular compound is also affected by other factors (a system of hydrogen bonds, S?S and S…Cl interactions between cluster complexes, packing effects etc.). 相似文献

Reactions of the rigid–flexible N-heterocycle 1,3-bis(5-(pyridine-2-yl)-1,2,4-triazole-3-yl) propane (H2L) with MCl2 (M = Fe, Co, Cu or Zn) gave coordination complexes, {[Fe 2 III Cl4(H2L)2]·2Cl}·EtOH·H2O (1), {[Co3Cl5(HL)]·H2O} n (2), {[Co4Cl4(H2L)2(H2O)4]·[CoCl4]2}·H2O (3), [Cu2Cl3(HL)(H2O)]6·5H2O (4), [Cu 2 II CuICl4(HL)] n (5), {[Zn2Cl2(L)H2O]·H2O} n (6) and [Zn4Cl6(HL)2] (7), which have been characterized by single-crystal X-ray diffraction. Structural analysis reveals that the pyridine triazole ligand attains versatile coordination modes in these complexes. Complexes 1, 3, 4 and 7 consist of 0D clusters with binuclear or tetranuclear units; complex 2 presents a 2D network accompanied by HL? and chloride bridges; complexes 5 and 6 show 1D chains with [Cu3] and [Zn2] subunits. In addition, the electrospray ionization mass spectrometry properties of selected complexes were investigated, revealing the stabilities and structural states of these complexes in solution. These results indicate that H2L is an excellent multiconnection linker for the construction of diverse coordination complexes. 相似文献

New octahedral anionic heterometal rhenium-osmium cluster complexes [Re5OsSe8(OH)6]3− and [Re4Os2Se8(OH)6]2− were synthesized starting from [Re5OsSe8Cl6]3− and [Re4Os2Se8Cl6]2−, respectively. They were isolated as salts of the compositions Cs3[Re5OsSe8(OH)6] · 11H2O (I), K3[Re5OsSe8(OH)6] · 7H2O (II), and K2[Re4Os2Se8(OH)6] · 3H2O (III). The protonation of the terminal OH ligands of [Re5OsSe8(OH)6]3− in an aqueous solution resulted in crystallization of a neutral complex [Re5OsSe8(H2O)3(OH)3] · 12H2O (IV). The compounds have been characterized by single-crystal X-ray diffraction analysis. The luminescence properties of [Re5OsSe8(OH)6]3− and [Re4Os2Se8(OH)6]2− were studied. In addition, the electronic structures of the complexes were elucidated by DFT calculations. 相似文献

Reaction of heterometal cuboidal clusters [Mo3(MCl)S4(H2O)9]3+ (M = Ni, Pd) with PhSO2Na in aqueous HCl leads to the substitution at Ni or Pd to give the [Mo3(M(PhSO2))(H2O)9—xClx](3—x)+species, isolated as supramolecular adducts with cucurbituril (Cuc) [Mo3(Ni(PhSO2))S4Cl1.17(H2O)7.83][Mo3(Ni(PhSO2))S4Cl2.22(H2O)6.78]Cl2.61 · Cuc · 15H2O ( 1 ) and [Mo3(Pd(PhSO2))S4Cl1.12(H2O)7.88][Mo3(Pd(PhSO2))S4Cl2.29(H2O)6.71]Cl2.59 · Cuc · 11H2O ( 2 ), respectively. Crystal structure of 1 and 2 was determined, revealing that the PhSO2 is coordinated via its sulfur atom (Ni — S 2.182 Å, Pd — S 2.305 Å). The structure of these isostructural compounds is built from triple aggregates {(cluster)(Cuc)(cluster)} united into zigzag chains via hydrogen bonds between coordinated PhSO2 and H2O ligands. 相似文献

Syntheses and Crystal Structures of Novel Chalcogenido‐bridged Niobium Copper Clusters In the presence of tertiary phosphines, the reaction of NbCl5 and Copper(I) salts with Se(SiMe3)2 (E = S, Se) affords the new chalcogenido‐bridged niobium‐copper cluster compounds ( 1 ) and [NbCu4Se4Cl (PPh3)4] ( 2 ). Using E(R)SiMe3 (E = S, Se, R = Ph, nPr) instead of the bisilylated selenium species leads to the compounds [NbCu2(SPh)6(PMe3)2] ( 3 ), [NbCu2(SPh)6(PnPr3)2] ( 4 ), [NbCu2(SePh)6(PMe3)2] ( 5 ), [NbCu2(SePh)6(PnPr3)2] ( 6 ), [NbCu2(SePh)6(PiPr3)2] ( 7 ), [NbCu2(SePh)6(PtBu3)2] ( 8 ), [NbCu2(SePh)6(PiPr2Me)2] ( 9 ), [NbCu2(SePh)6(PPhEt2)2] ( 10 ), [Nb2Cu2(SnPr)8(PnPr3)2Cl2] ( 11 ) and [Nb2Cu6(SnPr)12(PiPr3)2Cl4]·2 CH3CN ( 12 ·2 CH3CN). By reacting CuI salts and NbCl5 with the monosilylated selenides Se(tBu)SiMe3 and Se(iPr)SiMe3 which have a weak Se–C bond the products [Nb2Cu6Se6(PiPr3)6Cl4] ( 13 ), [Nb2Cu4Se2(SeiPr)6(PnPr3)4Cl2] ( 14 ) and [Nb2Cu6Se2(SeiPr)10(PEt2Me)2Cl2]·DME ( 15 ) are formed which contain selenide as well as alkylselenolate ligands.

The reactions of SnMe3Cl with salts of the cluster anionic complexes [Re6Q8(CN)6]4?

The title compound, hexaammonium tetra‐μ3‐selenido‐tetrakis(tricyanomolybdenum) hexahydrate, is isostructural with the Mo/S, W/S and W/Se analogues. The structure contains disordered cyclic hydrogen‐bonded [{(NH4)(H2O)}3]3+ cations and [Mo4Se4(CN)12]6? cluster anions with 3m symmetry. The cation assembly consists of alternating ammonium and water molecules linked by N—H?O hydrogen bonds. The anion has a typical cubane cluster structure. The cations and anions are linked together by hydrogen bonds involving the terminal N atoms of the CN groups. 相似文献

Reduction of ZrBr4 with HSnBu3 yielded a blue solid. When this blue solid was treated with PMe3, a hexanuelear cluster [Zr6Br14H4( PMe3)4] (2) was isolated. Reaction of the blue solid with [PPh4]Br in CH2Cl2 resulted in the formation of a paramagnetic and unstable cluster anion, [Zr6Br18H5]2– (3), which disproportionated to form a new cluster anion, [Zr6Br18H5]3– (4) and some Zr(IV) species. Compounds containing 4 can also be obtained from reaction of the blue solid with Br– in MeCN. Reduction of ZrCl4 with HsnBu3 gave a red–brown solid, and [Zr6Cl14H4(AsMe3)4] (9) and [Zr5Cl12H4(AsMe3)5](8) were obtained by reaction of the red–brown solid with AsMe3. No cluster compounds containing amine ligands were obtained in the reaction of the red–brown solid with amines; only compounds containing the [Zr6Cl18 H5]3– anion and ammonium cations were isolated. Altogether ten products were characterized by single crystal X-ray diffraction and where possible, by 1H NMR studies. 相似文献
