Bi(NO3)3 reacts with cucurbit[8]uril, (Q8), in 3M HNO3 to give the title complex whose structure includes three discrete Bi complexes: [{Bi(NO3)(H2O)5}2(Q8)]4+ (CN of Bi = 9, both NO3— and cucurbit[8]uril are bidentate), [Bi(NO3)5]2— (CN of Bi = 10, all NO3— are bidentate), and [Bi(NO3)3(H2O)4] (CN of Bi = 10, all NO3— are bidentate). 相似文献

The structure of the salt Cs[Gd(H2O)4Re6Te8(CN)6]·4H2O (space group P-1, a = 9.436(5) Å, b = 12.365(7) Å, c = 15.187(8)Å, α = 89.104(10)°, β = 86.996(10)°, γ = 82.304(9)°) has been established by single crystal XRD. The structure of the compound features layers involving Gd3+ cations bound to cluster anions [Re6Te8(CN)6]4? through cyanide groups. The interlayer space contains cesium cations and crystallization water molecules. 相似文献

The single crystals of Rb2[(UO2)2(C2O4)2(SeO4)] · 1.33H2O were synthesized and studied by X-ray diffraction. The crystals are monoclinic, space group P21/m, Z= 2, the unit cell parameters: a = 5.6537(8), b = 18.736(3), c = 9.4535(15) Å, β = 98.440(5)°, V = 990.6(3) Å3, R 1 = 0.0506. The main structural units of the crystal are infinite layers of [(UO2)2(C2O4)2(SeO4)]2?, corresponding to the crystal chemical group A2K 2 02 B2 (A = UO 2 2+ , K02 = C2O 4 2? , B2 = SeO 4 2? ) of uranyl complexes. The uranium-containing layers are united into a three-dimensional framework through the electrostatic interactions with the outer-sphere rubidium ions and the hydrogen bonding system involving the outer-sphere water molecules. 相似文献

Single crystals of a new modification of the di(nitrato)di(aqua)palladium(II) complex β-trans-[Pd(NO3)2(H2O)2] were obtained. Their crystal structure was determined: monoclinic crystal system, a = 5.7469(4) Å, b = 5.3942(6) Å, c = 10.0956(10) Å, β = 97.401(3)°, P21/c, Z = 2, d calc = 2.851 g/cm3, Bruker X8 APEX CCD, MoK α , 836 independent reflections, room temperature. The square-plane coordination of the Pd atom is formed by four oxygen atoms (Pd-O(NO3) 2.003(3) Å and Pd-O(H2O) 2.021(4) Å) and completed to a distorted bipyramid by two intramolecular contacts (Pd…O(NO3) 2.893 Å). A comparative crystal-chemical analysis with α-trans-[Pd(NO3)2(H2O)2] was carried out. 相似文献

Diffusion of aqueous solutions of K4[Re4Te4(CN)12] and CuCl2 in the opposite direction through silica gel gives rise to the new polymer-like compound 1 . This complex has a layered structure built from the interconnected cubane-like cluster cations [Cu4(μ3-OH)4]4+ and the cluster anions [Re4Te4(CN)12]4− (see picture). 相似文献
