摘要
A novel organic-inorganic hybrid pentaborate [Ni(C4H10N2)(C2H8N2)(2)][B5O6(OH)(4)](2) has been synthesized by hydrothermal reaction and characterized by FT-IR, Raman spectroscopy, elemental analyses and DTA-TGA. Its crystal structure was determined from single crystal X-ray diffraction The structure consists of isolated polyborate anion [B5O6(OH)(4)](-) and nickel complex cation of [Ni(C4H10N2)(C2H8N2)(2)](2+) in which the two kinds of ligands come from the decomposition of triethylenetriamine material. The [B5O6(OH)(4)](-) units are connected to one another through hydrogen bonds, forming a three-dimensional framework with large channel along the a and c axes, in which the templating [Ni(C4H10N2)(C2H8N2)(2)](2+) cations are located. The assignments of the record FT-IR absorption frequencies and Raman shifts were given. (c) 2005 Elsevier B.V. All rights reserved.
