摘要:
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 center dot center dot center dot N(bpe) and O-Hw center dot center dot center dot S(thiocyanate) hydrogen bonds. The intermetallic M center dot center dot center dot M distances are 6.90 and 6.87 angstrom for 1 and 2, respectively. Supramolecular architectures are obtained by connections through H-bonds. Slight interactions are observed for compound 2. (C) 2011 Elsevier Ltd. All rights reserved.
