Abstract
Two new borate clusters, [C4H11N2O][C4H9N2][B5O6(OH)4]2 (1), [Cd(dien)2][B5O6(OH)4]2 (2, dien = diethylenetriamine), have been obtained under solvothermal conditions and characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis, powder X-ray diffraction and single-crystal X-ray structural analysis, respectively. Crystal data for 1: monoclinic, P21/c, a = 18.6975(5) Å, b = 15.3413(8) Å, c = 9.6691(3) Å, β = 90.462(3)°, Z = 4. Crystal data for 2: triclinic, P-1, a = 8.6107(4) Å, b = 9.3504(4) Å, c = 18.9631(4) Å, α = 103.798(4), β = 91.940(4)°, γ = 94.134(4)°, Z = 2. They all consist of [B5O6(OH)4]− clusters and further extend to 3-D frameworks via extensive hydrogen-bonding interactions. Interestingly, a novel in situ organic reaction between ethylenediamine and CH3COO− group has been observed during the formation of compound 1.
