Our recent research focused on the synthesis and investigation of 1D and 2D coordination polymers mostly based on stable hexanuclear building blocks of the type [MnIII2MnII4O2(RCOO)10] (R=CHMe2, CMe3) [1,2]. Most of these compounds were synthesized by the reaction of manganese(II) isobutyrate, [Mn6(CHMe2)12(OCCHMe2H)6] [3]. Herein we demonstrate that by using the same hexanuclear manganese(II) precursor, it is possible to obtain a discrete 2D coordination polymer that for the first time is not based on {Mn6} building blocks, namely [Mn(CHMe2)2(bpe)(H2O)]n (bpe = 1,2-bis(4-pyridyl)ethane). Single-crystal X-ray diffraction analysis shows that each manganese(II) center is coordinated by two bridging bidentate isobutyrates, one deprotonated monodentate isobutyrate (as evident from the short C=O bond length of 1.246 Å), and one coordinated water molecule resulting in 1D zigzag chains. Two additional bpe ligands at each manganese(II) center interlink the 1D zigzag chains into a 2D network structure (Figure). The magnetic studies will be presented in a full paper.figre
