Solvent-free synthesis of new metal phosphites with double-layered, pillared-layered, and framework structures

Crystal structure, IR, Raman and UV–Vis studies of [Co(H2P2O7)2(H2O)2][CH3)3C-NH3)]2·2H2O

“…Besides, large number of studies have been devoted to the preparation of new organic inorganic metal phosphates, which combine the robustness of phosphate group and the versatility of organic template giving rise to various architectures and excellent properties [12][13][14][15][16][17]. In contrast to numerous hybrid organic inorganic metal phosphates and phosphites reported [18][19][20][21][22], the structural chemistry of homologous pyrophosphates is relatively rare. Within our research group, we published the synthesis and crystal structure of (NH 3 (CH 2 ) 2 NH 3 ) 2 [Me(HP 2 O 7 ) 2 •2H 2 O] [Me = Mg [23], Co, Ni [24] and Ln 2 (NH 2 (CH 2 ) 2 NH 2 )(HP 2 O 7 ) 2 •4H 2 O (Ln=Eu, Tb, Er) [25].…”

Ionothermal synthesis and magnetic study of a new manganese(ii) phosphite with an unprecedented Mn/P ratio

“…So far, the reported Mn/P ratios include 1/1, 1/2, 1/4, 1/6, 2/5, 2/7, 3/4, 5/2 and 11/8 (ESI Table S1 †). [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] Considering the large variety of combinations of Mn-and P-centred polyhedra, one may expect that more manganese phosphites with different Mn/P ratios could be found in the future. Here, we report the synthesis of a new manganese phosphite (NH 4 ) 4 [Mn 4 (HPO 3 ) 6 ] (JIS-10) by using 1-pentyl-3-methylimidazolium bromide ([Pmim]Br) as the ionic liquid solvent.…”
