Manganese(III) Formate: A Three-Dimensional Framework That Traps Carbon Dioxide Molecules

Abstract

Carbon dioxide, formic acid, and water molecules are trapped in the crystal lattice of manganese(III) formate (see 1), which was obtained by reducing permanganate with formic acid. Each CO guest molecule exhibits four C-H⋅⋅⋅O-C-O interactions with the three-dimensional host framework of Mn(HCOO) units. Compound 1 undergoes an antiferromagnetic phase transition at 27 K.

Structurally simple complexes of CO2

“…[33][34][35][36] Adsorption of CO2 into a framework generated by octahedral manganese(III) atoms bridged by formate ions has been reported. 37 The crystal structure reveals the formation of C-H···O hydrogen bonds between carbon dioxide and the hydrogen atom of the formate, a factor likely driving the adsorption. In fact, several other CO2 inclusion complexes of metal formates feature such interactions.…”

Aspects of carbon dioxide utilization

“…Therefore, it is required to find highly reactive metal catalysts. The investigations of the reaction between carbon dioxide and metal compounds, as transition elements, e.g., Ni [5][6][7][8][9], Pd [10,11], Pt [22], Co [12,55], Rh [13,14,22,34], Ir [15][16][17][18], Fe [19][20][21]34,53], Ru [22][23][24][25][26]34,53], Mn [27][28][29], Re [27,[30][31][32][33][34], Cr [35], Mo [35][36][37][38][39], W [35,[38][39][40][41], V …”

New double formates Na3M(HCOO)6 (M=Ga, In) with diamond-like metal framework: Synthesis, structure and coordination modes

“…Metal formates have attracted considerable attention due to their novel structures and interesting properties such as magnetism, absorption and separation [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. As the smallest and simplest carboxylate, formate has less stereo effect that can coordinate to metal cations as mono-, bis-, tri-or higher chelate ligands with various connection modes.…”
