The interaction of Mn II ions with acetate in a chemical environment provided by a decomposition reaction of the Schiff base 2‐(1‐hydroxy‐2‐methylpropan‐2‐ylimino)‐1,2‐di‐phenylethanone gave a 3D Mn II framework [Mn 5 (μ 3 ‐OH) 2 (CH 3 COO) 8 ] · 2CH 3 CH 2 OH ( 1 ). This was characterized by infrared spectroscopy, elemental analysis and powder X‐ray diffraction patterns, and structurally determined by single‐crystal X‐ray diffraction analysis. The title compound features two kinds of unprecedented tube‐in‐tube dihelical Mn II chains with opposite chiralities. They are alternatively arranged and bridged by Mn II ions linked by acetate ions to form a 3D framework with a rare heptanodal topology. Magnetic studies revealed that compound 1 shows spin‐canted and metamagnetic behavior. This work affords a synthetic strategy incorporating the decomposition reaction of a Schiff base which provides the chemical environment for another reaction and to direct the formation of the title compound and its crystals.
