(Figure Presented) Singles networks: The use of 1,3-propanediol and of 2-methyl-1,3-propanediol in manganese carboxylate chemistry leads to two new 3D coordination polymers with an unprecedented Mn19 repeating unit. The polymers have open framework structures with nanometer-sized cavities (see picture; Na not visible, Mn blue, O red, C gray). The Mn19 units have a ground spin state of S = 23/2 and behave as single-molecule magnets.
