Abstract
Hydrothermal reaction of a mixture of $MnC_2O_4, H_3PO_3$, piperazine and water at 423 K for 72h resulted in a new inorganic–organic hybrid phase, $[C_4N_2H_{12}][Mn^{II}\hspace{1mm}_2(HPO_3)_2(C_2O_4)]$, I. The structure comprises a network of $Mn_2O_{10}$ dimers, $HPO_3$ psuedo-tetrahedra and oxalate units, connected through their vertices forming a three-dimensional structure with one-dimensional channels. Protonated piperazine molecules are found in the channels. The formation of $Mn(HPO_3)_\infty$ layers using only one type of secondary building unit, SBU-4, is noteworthy. Detailed magnetic investigations reveal that the antiferromagnetic layers are coupled in such a way to show magnetic polarizations on application of high magnetic field at low temperatures. This is unique and to the best of our knowledge has been observed for the first time in an open-framework solid.
