The anionic layers are stacked perpendicularly to the c axis of the unit cell forming two-dimensional channels between the layers. The [C4H9NH3]^+ cations interdigitate in a bilayer and reside in the 2D channels leading to a sandwich-like arrangement of the anion and cations. 展开更多

Solvothermal reaction of Pb(NO3)2·6H2O with rigid linear ligand terephthalic acid(H2pta) in N,N-dimethylformamide(DMF) produced a new three-dimensional(3D) lead(Ⅱ)coordination polymer[Pb2(pta)1.5(μ4-OH)(DMF)]n 1,and its structure was characterized by single-crystal X-ray diffraction analyses.In polymer 1,the μ4-OH bridges the nearby lead(Ⅱ) ions into an infinite one-dimensional(1D) chain,and then the organic ligand pta^2- joins the neighbored chains into a 3D structure by two similar connection modes in different configurations.The solid-state photoluminescent studies revealed that 1 exhibits a strong greenish emission mainly originating from ligand-to-metal charge transfer between the delocalized π bonds of the aromatic carboxylate ligand pta^2- and the p orbitals of the Pb^2+ centers. 展开更多

The structure con- sists of [(VO)6(B10O22)2]15- cluster anions that have a central band of six trans-edge-sharing VO5 square pyramids capped by two [B10O22]14- polyborate ligands. Other characterizations are also describ- ed by elemental analysis, IR spectrum and thermal analysis. 展开更多

New hydrated potassium hexaborate K2[B6O9(OH)2] has been synthesized under mild solvothermal conditions. The structure was determined by single-crystal X-ray diffraction and further characterized by FT-IR, Rarnan spectra and DTA-TG. It crystallizes in the monoclinic system with space group P21/n, a=0.9036(2) nm, b=0.66052(18) nm, c=1.5997(4) nm, β=91.862(4)°, V=0.9543(4) nm^3 and Z=4. Its crystal structure consists of K-O polyhedra and 1-D stepped polyborate chains constructed by new [B6O9(OH)2]2- fundamental building blocks. 1-D polyborate chains contain 3,8-membered boron rings. Adjacent chains are further linked via H-bonding interactions into 2-D layers. The K^+ cations reside not only between the layers but also in the 8-membered boron rings of the chains, compensating the negative charges of the borate chains and holding the layers together into the 3-D structure through bonding with oxygen atoms of the chains. 展开更多

A new hydrated lithium borate, Li4[B8O13(OH)2]·3H2O, has been hydrothermally synthesized and characterized by single crystal X-ray diffraction, FT-IR spectroscopy, simultaneous TGA-DTA and chemical analysis. It crystal- lizes in the triclinic, space group P]-, a=8.4578(5) A, b=8.7877(5) A, c= 10.8058(7) A, a=87.740(3)°, β= 71.819(3)°, γ=61.569(3)°, Z=2, V=665.26(7) A3, Dc=2.043 g/cm3. Its crystal structure features polyborate ani- onic layers with the larger odd 13-membered boron rings constructed by [B8O13(OH)2]4- FBBs. Through designing the thermochemical cycle, the standard molar enthalpy of formation of this borate was determined to be -(7953.8 ± 6.6) kJ·mol-1 by using a heat conduction microcalorimeter. 展开更多
