Crystal structure and spectral studies of a novel manganese(II) complex of 4-phenyl-2-acetylpyridine thiosemicarbazone: Extended network of [Mn(Ac4Ph)2] via hydrogen bond linkages and π-π interactions

The reaction of Mn(CH3COO)2 · 4H2O with 4-phenyl-2-acetylpyridine thiosemicarbazone, HAc4Ph, yielded the novel six-coordinate complex [Mn(Ac4Ph)2]. The complex has been characterized by spectral (IR and EPR) and X-ray diffraction methods. Intermolecular hydrogen bonds of the DAAD type and π-π interactions stabilize the structure and result in the formation of infinite layers.
