摘要
A new layered manganese(II)phosphite,|NH_(4)|_(4)[Mn_(4)(PO_(3)H)_(6)](JIS-10),has been synthesised via the ionothermal method by using 1-pentyl-3-methylimidazolium bromide([Pmim]Br)as the solvent.JIS-10 is the first manganese phosphite with a Mn/P ratio of 2/3,whose layered framework is built by the alternate connection of Mn_(2)O_(9)dimers and PO3H pseudo-tetrahedra.JIS-10 represents an antiferromagnetic dimer system with S=5/2 for each Mn^(2+)ion.
