The reaction of CCl₃CN and ammonia in the presence of metal salts [Ni(CH₃COO)₂, CuCl₂ or Pd(CH₃COO)₂] in DMSO afforded mononuclear complexes of general formula {M[NH = C(CCl₃)NC(CCl₃) = NH]₂}[(CH₃)₂SO]₂ [M = Ni(g class=""boldFont"">1g>), Cu(g class=""boldFont"">2g>), Pd(g class=""boldFont"">3g>)]. The complexes were characterized by ESI-MS, IR spectroscopy, elemental and single-crystal X-ray diffraction analyses. In g class=""boldFont"">1g>-g class=""boldFont"">3g>, the metal atom is in an inversion centre and possesses a square-planar coordination environment with two uninegatively charged 1,3,5-triazapentadienato chelators. In the solid state, the (N)H atoms of the ligands interact with oxygen atoms of (CH₃)₂SO with formation of the six-membered intermolecular resonance assisted hydrogen bonding, while Cl atoms of the CCl₃ groups participate in Cl?Cl interactions thus generating 2D supramolecular assembly of distinctive geometry.
