Abstract:  The title compound, Ni(NCS)2(2,5-diMepy)2, crystallizes in monoclinic system: space group P2Jc, two molecules per unit cell of а = 8.785(3), b=5.279(3), с=19.603(20) x 10^-10 m, and β= 93.28(5)° dimensions. The crystal structure was solved using the heavy-atom method and refined by the method of full matrix least squares leading to the final R value of 0.062. The central atom of the molecular complex was located at the centre of symmetry and it was surrounded in an approximately square-planar arrangement by four nitrogen atoms of the ligands at Ni—N distances of 1.865 (NCS group) and 1.910 x 10^-10 m (2,5-diMepy), respectively. Ni(NCS)₂(2,5-diMepy)₂ molecules were held together by contacts of S atoms with dimethylpyridine rings of the neighbouring complex molecules.
