Abstract

Graphical abstract: Self-assembly reaction of [Mn(CH3 COO)2 ·4H2 O], K[N(Ph2 PO)2 ] with mono- or bi-pyridines led to construction of mono-, di-, tetra-, and poly-nuclear manganese(II) complexes with tetraphenylimidodiphosphinates under controlled reaction conditions. Abstract: Treatment of [Mn(CH3 COO)2 ·4H2 O] with two equivalents of K[N(Ph2 PO)2 ] in the presence of two equivalents of pyridine (py) or 4- t Bu-pyridine (4- t Bu-py) in MeOH–H2 O afforded mononuclear complexes [Mn{N(Ph2 PO)2 }2 (py)2 ]·2H2 O (1 ) and [Mn{N(Ph2 PO)2 }2 (4- t Bu-py)2 ] (2 ), respectively. Interaction of [Mn(CH3 COO)2 ·4H2 O] with two equivalents of K[N(Ph2 PO)2 ] in the presence of one equivalent of rigid dipyridyl-based ligand 4, 4′-bipyridine (bpy) or trans -1, 4-bis-(pyridyl)ethene (bpe) resulted in formation of one-dimensional linear polymeric chains [Mn{N(Ph2 PO)2 }2 ( μ -bpy)] n (3 ) and [Mn{N(Ph2 PO)2 }2 ( μ -bpe)·2CH2 Cl2 ] n (5 ), respectively. Reaction of [Mn(CH3 COO)2 ·4H2 O] with each of one equivalent of K[N(Ph2 PO)2 ] and K[Ph2 PO2 ] in the presence of one equivalent of bpy afforded a polymeric complex [Mn{N(Ph2 PO)2 }2 ( μ -bpy)] n -[Mn2 {N(Ph2 PO)2 }2 ( μ -Ph2 PO2 )2 ( μ -bpy)] n (4 ) which contains two independent one-dimensional linear polymeric chains. Self-assembly reaction of [Mn(CH3 COO)2 ·4H2 O], K[N(Ph2 PO)2 ], bpy and bpe in a 1:2:1:1 ratio gave a dinuclear complex [Mn(bpe){N(Ph2 PO)2 }2 ]2 ( μ -bpy)·H2 O (6 ). Self-assembly reaction of [Mn(CH3 COO)2 ·4H2 O], K[N(Ph2 PO)2 ], and a flexible dipyridyl-based ligand 4, 4′-trimethylenedipyridine (tmpy) in a 1:2:1 ratio gave a tetranuclear complex [Mn{N(Ph2 PO)2 }2 ( μ -tmpy)]4 ·2CH3 OH·3H2 O (7 ). All complexes are air-stable in the solid-state, and were well characterized by electronic, infrared and mass spectroscopies along with thermogravimetric analyses, and their molecular structures have been well established by X-ray crystallography.
