Title: Hydrothermal synthesis, crystal structure, and magnetic properties of a novel organo-templated iron(III) borophosphate: (C{sub 3}H{sub 12}N{sub 2})Fe{sup III} {sub 6}(H{sub 2}O){sub 4}[B{sub 4}P{sub 8}O{sub 32}(OH){sub 8}]

The organo-templated iron(III) borophosphate (C{sub 3}H{sub 12}N{sub 2})Fe{sup III} {sub 6}(H{sub 2}O){sub 4}[B{sub 4}P{sub 8}O{sub 32}(OH){sub 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, P2{sub 1}/c (No. 14), a=5.014(2) A, b=9.309(2) A, c=20.923(7) A, beta=110.29(2){sup o}, V=915.9(5) A{sup 3}, Z=2, R1=0.049, wR2=0.107 for all data, 2234 observed reflections with I>2sigma(I)). The title compound contains a complex inorganic framework of borophosphate trimers [BP{sub 2}O{sub 8}(OH){sub 2}]{sup 5-} together with FeO{sub 4}(OH)(H{sub 2}O)- and FeO{sub 4}(OH){sub 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 T{sub N}{approx}14.0(1) K. - Graphical abstract: The complex inorganic open-framework of (C{sub 3}H{sub 12}N{sub 2})Fe{sup III} {sub 6}(H{sub 2}O){sub 4}[B{sub 4}P{sub 8}O{sub 32}(OH){sub 8}] consists of borophosphate trimers and iron(III) coordination octahedra arranged to form channels with ten-membered ring apertures in which the organic 1,3-diaminopropane cations are located.
