New coordination polymers based on 2-methylimidazole and transition metal nitroprusside containing building blocks: Synthesis, structure and magnetic properties
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...
