A new zinc borate [Zn(dap)2][B4O6(OH)2] (1, dap = 1,3-diaminopropane) has been hydrothermally synthesized and structurally characterized by IR, elemental analysis, thermogravimetric analysis, powder and single-crystal X-ray diffractions. It crystallized in the monoclinic P21/c space group, a = 7.0050(4) Å, b = 7.8160(2) Å, c = 18.4470(5) Å, β = 94.571(3) Å, V = 1006.78(7) Å3, Z = 4, R1 = 0.0342, wR2 = 0.0835. Compound 1 displays a novel two-dimensional inorganic–organic hybrid zinc borate layer constructed from the assembly of [B4O6(OH)2]2− clusters, ZnO2N2 tetrahedra and organic dap molecules. The occurrence of infinite Zn–amine–Zn chains in the structure is uncommon and noteworthy in borate materials.
