DOIAbstract
Four coordination polymers obtained by the intercalation of 2-methylimidazole into transition metal nitroprussides T[Fe(CN)5NO] with T = Mn, Fe, Co and Ni were synthesized and characterized. The resulting hybrid inorganic-organic solids crystallize as dihydrates. All the solids were crystallized in an orthorhombic crystal system in the space group P212121. Their crystal structures were solved and refined from X-ray diffraction data, complemented by structural information derived from spectroscopic (IR, Raman and UV-Vis) and thermal data. The intercalated molecules occupy the axial coordination sites of the metal T(ii), while the Fe atom of the nitroprusside anion preserves the octahedral coordination geometry. In the interlayer region, the ...
