Abstract

Two new pentaborates, [Zn(DIEN)₂][B₅O ₆(OH)₄]₂ (DIEN=diethylenetriamine) (I) and [B₅O₇(OH)₃Zn(TREN)] (TREN=tris(2-aminoethyl) amine) (II), have been hydrothermally synthesized and characterized by single crystal X-ray diffraction, FTIR, elemental analysis and thermogravimetric analysis. Compound I crystallizes in the monoclinic system, space group P2 ₁/c (No. 14), a=8.5686(2)Å, b=11.7883(3)Å, c=14.5407(6)Å, β=91.259(2)°, V=1468.39(8)Å3, Z=2. The structure consists of isolated borate polyanion [B₅O ₆(OH)₄]^- and zinc complex cation [Zn(DIEN) ₂]²⁺. The anionic units, [B₅O ₆(OH)₄]^-, are linked by hydrogen bonds to form a 3D supramolecular network containing large channels, in which the templating [Zn(DIEN)₂]²⁺ cation are located. II is monoclinic, P2₁/c (No. 14), a=8.9969(2)Å, b=20.6903(6)Å, c=9.2878(3)Å, β=99.635(2)°, V=1704.52(8)Å3, Z=4. The structure of II is constructed from two distinct motifs, a usual [B ₅O₇(OH)₃]^2- cluster and a supporting zinc complex [Zn(TREN)]²⁺, which are integrated through Zn-O-B linkage. This compound represents the first example of the combination of B-O cluster with transition-metal complex.
