N2 - Two new tetraborates, namely [Li(H2O)4]2[Cu(H2O)6][Cu(H2O)5]2[B4O5(OH)4]4·4H2O (1) and [Cu(en)2(H2O)2][Cu(en)2(B(OH)3)2][B4O5(OH)4]2·H2O (2) have been made under solvothermal conditions and characterized by FT-IR spectroscopy, powder X-ray diffraction, single crystal X-ray diffraction and thermogravimetric analysis, respectively. 1: triclinic, Pī, a = 7.0400(2) Å, b = 7.8779(3) Å, c = 25.8958(11) Å, α = 90.827(3)º, β = 95.985(3)º, γ = 105.816(3)º, Z = 1. 2: monoclinic, P2/c, a = 12.5723(6) Å, b = 9.1508(5) Å, c = 15.9800(6) Å, β = 94.742(4)º, Z = 2. In structure 1, the B4O5(OH)4 clusters join together via H-bonding interactions to produce 3-D supramolecular framework with three types of channels located by the Cu(H2O)6, Cu(H2O)5 and Li(H2O)4 polyhedra, respectively. While in 2, the B4O5(OH)4 clusters link each other to form 2-D layers and then further pillared by Cu(en)2(B(OH)3)2 complexes via H-bonding interactions, resulting in 3-D supramolecular framework with hexagonal and rectangle channels, in which the rectangle channels are filled by Cu(H2O)2(en)2 complexes.
