| Abstract: | The organo-templated iron(III) borophosphate (C3H12N2)FeIII 6(H2O)4B4P8O32(OH)8] was prepared under mild hydrothermal conditions (at 443 K) and the crystal structure was determined from single crystal X-ray data at 295 K (monoclinic, P21/c (No. 14), a=5.014(2) Å, b=9.309(2) Å, c=20.923(7) Å, β=110.29(2)°, V=915.9(5) Å3, Z=2, R1=0.049, wR2=0.107 for all data, 2234 observed reflections with I>2σ(I)). The title compound contains a complex inorganic framework of borophosphate trimers BP2O8(OH)2]5− together with FeO4(OH)(H2O)- and FeO4(OH)2-octahedra forming channels with ten-membered ring apertures in which the diaminopropane cations are located. The magnetization measurements confirm the Fe(III)-state and show an antiferromagnetic ordering at TN≈14.0(1) K. |
