In this study, three new complexes (4aepyH)(2)[Ni(CN)(4)] (1), (4aepyH)(2)[Pd(CN)(4)] (2) and (4aepyH)(2)[Pt(CN)(4)] (3) [4aepy = 4-(2-aminoethyl)pyridine] have been synthesized and characterized by elemental, thermal, vibrational (FT-IR and Raman) and single-crystal X-ray diffraction techniques. The crystallographic analyses reveal that the complexes crystallize in the monoclinic system, space group C2/c. The asymmetric units of the complexes contain one M(II) ion, two cyanide ligands and one non coordinated the 4aepy ligand. Each M(II) ion is four coordinated with four cyanide-carbon atoms in a square planar geometry and the [M(CN)(4)](2-) anions act as a counter ion. The 4aepyH cations in the complexes compose of the protonation of the 4aepy. The vibrational spectral data also supported to the crystal structures of the complexes. Thermal stabilities and decomposition products of the complexes were investigated in the temperature range 40-700 degrees C in the static air atmosphere. (C) 2017 Elsevier B.V. All rights reserved.
