Four new thioantimonates(III) with compositions [(C3H10NO)(C3H10N)][Sb8S13] ( 1 ) (C3H9NO = 1‐amino‐3‐propanol, C3H9N = propylamine), [(C2H8NO)(C2H8N)(CH5N)][Sb8S13] ( 2 ) (C2H7NO = ethanolamine, C2H7N = ethylamine, CH5N = methylamine), [(C6H16N2)(C6H14N2)][Sb6S10] ( 3 ) (C6H14N2 = 1,2‐diaminocyclohexane) and [C8H22N2][Sb4S7] ( 4 ) (C8H20N2 = 1,8‐diaminooctane) were synthesized under solvothermal conditions. Compound 1 : triclinic space group P$\bar{1}$ , a = 6.9695(6) Å, b = 13.8095(12) Å, c = 18.0354(17) Å, α = 98.367(11), β = 96.097(11) and γ = 101.281(11)°; compound 2 : monoclinic space group P21/m, a = 7.1668(5), b = 25.8986(14), c = 16.0436(11) Å, β = 96.847(8)°; compound 3 : monoclinic space group P21/n, a = 11.6194(9), b = 10.2445(5) Å, c = 27.3590(18) Å, β = 91.909(6)°; compound 4 : triclinic space group P$\bar{1}$ , a = 7.0743(6), b = 12.0846(11), c = 13.9933(14) Å, α = 114.723(10), β = 97.595(11), γ = 93.272(11)°. The main structural feature of the two atoms thick layered [Sb8S13]2– anion in 1 are large nearly rectangular pores with dimensions 11.2 × 11.7 Å. The layers are stacked perpendicular to [100] to form tunnels being directed along [100]. In contrast to 1 the structure of 2 contains a [Sb8S13]2– chain anion with Sb12S12 pores measuring about 8.9 × 11.5 Å. Only if longer Sb–S distances are considered as bonding interactions a layered anion is formed. The chain anion [Sb6S10]2– in compound 3 is unique and is constructed by corner‐sharing SbS3 pyramids. Two symmetry‐related single chains consisting of alternating SbS3 units and Sb3S3 rings are bound to Sb4S4 rings in chair conformation. Finally, in the structure of 4 the SbS3 and SbS4 moieties are joined corner‐linked to form a chain of alternating SbS4 units and (SbS3)3 blocks. Neighboring chains are connected into sheets that contain relatively large Sb10S10 heterorings. The sheets are further connected by sulfur atoms generating four atoms thick double sheets.  相似文献

The title complexes, catena‐poly[[aqua(1,10‐phenanthroline‐κ2N,N′)­cobalt(II)]‐μ‐benzene‐1,4‐di­carboxyl­ato‐κ2O1:O4], [Co(C8H4O4)(C12H8N2)(H2O)], (I), and catena‐poly[[[(di‐2‐pyridyl‐κN‐amine)copper(II)]‐μ‐benzene‐1,4‐di­carboxyl­ato‐κ4O1,O1′:O4,O4′] hydrate], [Cu(C8H4O4)(C10H9N3)]·H2O, (II), take the form of zigzag chains, with the 1,4‐benzene­di­carboxyl­ate ion acting as an amphimonodentate ligand in (I) and a bis‐bidentate ligand in (II). The CoII ion in (I) is five‐coordinate and has a distorted trigonal–bipyramidal geometry. The CuII ion in (II) is in a very distorted octahedral 4+2 environment, with the octahedron elongated along the trans O—Cu—O bonds and with a trans O—Cu—O angle of only 137.22 (8)°.  相似文献

Employing achiral organic amines (2-methylbenzimidazole and 1,4-diazabicyclo[2.2.2]octane) as the structure-directing agent and ligand, two chiral zincophosphites, [Zn(C(8)H(8)N(2))(HPO(3))] 1 and (C(6)H(13)N(2))[Zn(3)(C(6)H(12)N(2))(HPO(3))(3)(H(2)PO(3))] 2, have been hydro(solvo)-thermally synthesized, crystallizing in the chiral space group P2(1)2(1)2(1). Single-crystal structural analysis reveals that compound 1 consists of alternating ZnO(3)N and HPO(3) units exhibiting a neutral one-dimensional chiral chain. Interestingly, the organic ligands interact with the inorganic chain via hydrogen-bonds in hydrogen-bonded helix fashion. Compound 2, a three-dimensional chiral open framework with 16-MR channels, is formed by the distorted {Zn(3)P(4)} secondary building unit (SBU). The organic amine molecules play dual roles as both ligands and countercations.  相似文献

The thermal behavior of the complex Pr[(C5H8NS2)(C12H8N2)] in a dry nitrogen flow was examined by TG-DTG analysis. The TG-DTG investigations indicated that Pr[(C5H8NS2)(C12H8N2)] was decomposed into Pr2S3 and deposited carbon in one step where Pr2S3 predominated in the final products. The results of non-isothermal kinetic calculations showed that the decomposition stage was the random nucleation and subsequent growth mechanism(n = 2/3), the corresponding apparent activation energyE was 115.89 kJ•mol−1 and the pre-exponential constant In[A/s] was 7.8697. The empirical kinetics model equation was proposed as\(f(\alpha ) = \frac{3}{2}(1 - \alpha )[ - 1n(1 - \alpha )]^{\frac{1}{3}} \). The X-ray powder diffraction patterns of the thermal decomposition products at 800 °C under N2 atmosphere show that the product can be indexed to the cubic Pr2S3 phase. The transmission electron microscopy (TEM) of the final product reveals the particle appearance of a diameter within 40 nm. The experimental results show that the praseodymium sulfide nanocrystal can be prepared from thermal decomposition of Pr[(C5H8NS2)(C12H8N2)].

The title compound ZnS6(C12H8N2) was obtained by reaction of zinic powder with sulfur and 1,10-phenathtroline in DMF solvent, and its structure has been determined by single crystal X-ray diffraction analysis. The crystal data for the compound: triclinic, P-1, Z = 2, a = 8. 159(2), b = 9. 485(2), c = 11. 997(2)A , α =110. 00(3)°,β = 99.22(3)°, γ = 100.57(3)°, V = 832A3, Dc =1. 748g/cm3, μ(MoKa)=0. 2219 cm-1, F(000)=440. The structure was refined to R = 0. 0723 and Rw = 0. 0865 for 1427 independent observed reflections. The tilte crystal consists of a discrete molecules, in which the core of ZnS2N2 shows a distorted tetrahedral geometry.  相似文献

A new polymeric copper complex, viz.catena‐poly[[[μ‐N,N′‐bis(3‐amino­propyl)oxa­mid­ato‐κ6N,N′,O:N′′,N′′′,O′]­dicopper(II)]‐di‐μ‐dicyan­amido‐1:1′κ2N1:N5;2:2′κ2N1:N5], [Cu2(C8H16N4O2)(C2N3)2]n or [Cu(oxpn)0.5{N(CN)2}]n [where H2oxpn is N,N′‐bis(3‐amino­propyl)­ox­amide], has been ­synthesized by the reaction of Cu(oxpn), [Cu(ClO4)2]·6H2O and NaN3. In the crystal structure, the Cu atom is five‐coordinate and has a square‐pyrimidal (SP) configuration. In the polymer, dicyan­amide (dca) groups link CuII cations in a μ‐1,5‐bridging mode, generating novel ladders in which each step is composed of dimeric [Cu2(oxpn)]2+ cations. Abundant hydrogen bonds connect the polymer ladders into a two‐dimensional network structure.  相似文献
