Abstract
Two manganese(II) coordination polymers, namely, [Mn1.5(BCB)(bpy)1.5(H2O)]n (1), and [Mn(HBCB)(bibp)2(H2O)] (2), were assembled from the mixed ligands of the flexible tripodal ligand of 3,5‐bis(2‐carboxylphenoxy)benzoic acid (H3BCB) and two rigid N‐donors [bpy = 4,4′‐bipyridine, and bibp = 4,4′‐bis(imidazolyl)biphenyl]. Their structures were determined by single‐crystal X‐ray diffraction analyses and further characterized by elemental analyses (EA), IR spectra, powder X‐ray diffraction (PXRD), and thermogravimetric (TG) analyses. Structural analysis reveals that complex 1 is a 3D (3,4,6)‐connected {5·62}2{56·64·7·82·92}{64·8·9} net based on two kinds of inorganic nodes of dinuclear {Mn2(COO)2} SBUs and Mn(2) ions. Complex 2 is a hydrogen bonds based 3D supramolecule with 6‐connected {412·63}‐pcu net. Besides, the variable‐temperature susceptibilities of 1 and 2 were investigated.
