Abstract

Here we report the synthesis and characterization by X-ray diffraction, FTIR, UV-Vis and EPR spectroscopies, and the magnetic measurements of two new compounds: [Mn(NCS)2(bpe)2(H2O)2] (1) and [Fe(NCS)2(bpe)2(H2O)2] (2) (bpe = 1,2-bis(4-pyridyl)ethylene). Single-crystal structure analyses reveals discrete octahedral metal units that are assembled into 2D sheets through O-Hw⋯N(bpe) and O-Hw⋯S(thiocyanate) hydrogen bonds. The intermetallic M⋯M distances are 6.90 and 6.87 for 1 and 2, respectively. Supramolecular architectures are obtained by connections through H-bonds. Slight interactions are observed for compound 2.
