Abstract
Two new complexes, [Mn(H2bptc)(2,2′-bpy)2] · 2H2O (1) and [Mn3(Hbptc)2(2,2′-bpy)3(H2O)8] · 2H2O (2) (H4bptc = biphenyl-2,5,2′,5′-tetracarboxylic acid, 2,2′-bpy = 2,2′-bipyridine), have been synthesized under hydrothermal conditions. Their structures have been characterized by single-crystal X-ray diffraction, elemental analyses, IR spectra, powder X-ray diffraction, and thermogravimetric analyses. Complexes 1 and 2 are both linked into 3-D supramolecular networks by non-covalent interactions (O–H ··· O, C–H ··· O, C–H ··· π, and π ··· π). Complexes 1 and 2 exhibit weak antiferromagnetic interactions.
