A series of metalloborophosphates Na{sub 2}[M {sup II}B{sub 3}P{sub 2}O{sub 11}(OH)].0.67H{sub 2}O (M {sup II}=Mg, Mn, Fe, Co, Ni, Cu, Zn) have been prepared hydrothermally and their structures have been solved by single-crystal diffraction techniques. They all crystallize in a hexagonal space group P6{sub 3} and form a 3D microporous structure with 12-membered ring channels consisted of octahedral (M {sup II}O{sub 6}), tetrahedral (BO{sub 4}, PO{sub 4}) and triangular (BO{sub 2}(OH)) units, in which the counter Na{sup +} cations and water molecules are located. The Na{sup +} cations are mobile and can be exchanged by Li{sup +} in a melt of LiNO{sub 3}. Their open frameworks are thermal stable up to about 500 deg. C. Completed solid solutions between two different transition metals can also be obtained. Magnetic properties of Na{sub 2}[M {sup II}B{sub 3}P{sub 2}O{sub 11}(OH)].0.67H{sub 2}O (M {sup II}=Mn, Co, Ni, Cu) have been investigated. - Graphical abstract: A series of metalloborophosphates Na{sub 2}[M {sup II}B{sub 3}P{sub 2}O{sub 11}(OH)].0.67H{sub 2}O (M {sup II}=Mg, Mn, Fe, Co, Ni, Cu, Zn) were synthesized under hydrothermal conditions (473 K). The structure consists of microporous 3D open framework with 12-membered ring channels composed of octahedral (M {sup II}O{sub 6}), tetrahedral (BO{sub 4}, PO{sub 4}) and triangular (BO{sub 2}(OH)) units.
