Abstract

Abstract: Three manganese–molybdenum/tungsten bimetallic coordination polymers, two 2D {{[μ4 ‐M(CN)8 ]2 [Mn(dmf)3 ]2 [Mn(dmf)4 ]}· 2DMF} n (M = W1, Mo2 ) and a 1D {{[μ4 ‐Mo(CN)8 ][Mn(dmf)4 ]2 }· (ClO4 )} n (3 ), were constructed from the reaction of the (Bu3 NH)3 [M(CN)8 ] (M = W, Mo) and Mn(ClO4 )2 · 6H2 O molecular building blocks in DMF solvent in the presence (for1 and2 ) or absence (for3 ) of the organic ligand bis(benzimidazol‐2′‐yl)pyridine. Single‐crystal X‐ray diffraction structure analysis indicated that compounds1 and2 both crystallize in the monoclinic crystal system with the P 21 / c space group and possess the same 2D network. The 2D layer structures of1 and2 have a (3, 4)‐connected 2‐nodal topology with the point symbol {4 2 · 6 3 · 8}{4 2 · 6}. Compound3 crystallizes in the tetragonal crystal system with the P 42 / m space group. All three compounds are further assembled into 3D supramolecular structures through intermolecular C–H··· N or C–H··· O hydrogen bonds. The magnetic susceptibility of compounds1 and3 was investigated in the temperature range of 2–300 K; these compounds exhibit typical ferrimagnetic properties. Abstract : 2D coordination polymers {{[μ4 ‐M(CN)8 ]2 [Mn(dmf)3 ]2 [Mn(dmf)4 ]}· 2DMF} n (M = W, Mo) and a 1D chain compound {{[μ4 ‐Mo(CN)8 ][Mn(dmf)4 ]2 }· (ClO4 )} n are constructed by external‐template‐assisted formation in the presence and absence of bis(benzimidazol‐2′‐yl)pyridine. All three compounds can be assembled into 3D supramolecular structures, and two of the compounds exhibit typical ferrimagnetic properties.
