Popis:	The interaction of MnII 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 MnII framework [Mn5(μ3-OH)2(CH3COO)8]·2CH3CH2OH (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 MnII chains with opposite chiralities. They are alternatively arranged and bridged by MnII 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.
