Three different bis(ethylenediamine) Copper(II) tetraborates have been prepared: Cu(en)2[B4O5(OH)4] · 2B(OH)3 (A), 2{Cu(en)2B(OH)3 · H2O[B4O5(OH)4]} · H2O (B) and {Cu(H2O)2[B4O5(OH)4]2}(μ-H2O){Ag(en)2} · (μ-H2O){Na(H2O)2) (C). The crystal structure analyses of A (monoclinic, P21/c, a = 1282.5(1), b = 1020.8(1), c = 1510.5(2) pm; β = 96.66(1)°, Z = 4), B (monoclinic, Pc, a = 1254.4(1), b = 914.1(1), c = 1594.2(2) pm; β = 94.79(1)°, Z = 2) and C (triclinic, P1, a = 846.3(3), b = 917.9(3), c = 928.1(7) pm; α = 93.71(6)°, β = 104.79(3)°, γ = 103.23(2)°; Z = 1) show that all compounds contain the tetraborate ion [B4O5(OH)4]2-. In A and B, there are tetraborate ions and boric acid molecules. The coordination sphere of the Cu2+ ion is Jahn-Teller distorted, coordinated by 2 en groups with 4 Cu-N distances between 196 and 206 pm, as well as by 2 OH groups with Cu-O distances of 251 to 274 pm. In C, the Cu2+ ion is surrounded by 6 OH groups, and the Ag+ ion by 2 en and 2μ-H2O molecules.

AbstractLi3Y(BO3)2 was prepared by high-temperature solid state synthesis at 900°C in a platinum crucible from lithium carbonate, boric acid, and yttrium(III) oxide. The compound crystallizes monoclinically in the space group P21/c (no. 14) (Z=4) isotypically to Li3Gd(BO3)2. The structure was refined from single-crystal X-ray diffraction data: a=8.616(3), b=6.416(3), c=10.014(2) Å, β=116.6(2)°, V=494.9(3) Å3, R1=0.0211, and wR2=0.0378 for all data. The crystal structure of Li3Y(BO3)2 consists of [Y2O14] dinuclear units, which are interconnected to each other by planar B(1)O3 groups and LiO4 tetrahedra via common edges and corners along the a axis.
