Abstract

Two new Mn(II) coordination polymers with bis(5-tetrazolyl)methane (H 2btm), [Mn(btm)(phen)(H 2O)] · H 2O ( 1) and [Mn(btm)(2,2′-bpy)] · 1.5H 2O ( 2), have been synthesized and their structures determined by X-ray diffraction. In complex 1, the btm ligands assume the μ 2-1,1′:4 coordination mode and interlink Mn(II) ions into infinite one-dimensional chains. The chains are assembled into a three-dimensional architecture via hydrogen bonds and π–π interactions. For 2, Mn(II) ions are connected by btm ligands in the μ 3-1,1′:2:3′ mode to produce two-dimensional (6,3) coordination network. Magnetic investigations revealed that interactions through the btm bridges in both 1 and 2 are antiferromagnetic.
