Template synthesis, structure and magnetic property of a new open-framework manganese borophosphate: (C4N2H12)Mn[B2P3O12(OH)]

A new manganese borophosphate compound, (C4N2H12)Mn[B2P3O12(OH)], has been hydrothermally synthesized, and structurally determined. Its structure contains 1-D infinite loop-branched borophosphate chains, which are interconnected by MnO6 octahedral groups to construct a three-dimension open-framework with unidimensional channels. Magnetic measurement reveals an antiferromagnetic interaction system.
