The complexes of Ni (NCS) _2 · 4H_2O, Ni (NO) · 6H_2O with 1,7,10,16-tetraoxa-4,13-diazacyclooctadecane were reported in this paper. The d-d transitions of Ni (Ⅱ) ions were assigned according to the electronic spectra by means of Fourier transform infrared spectroscopy, conductivity, electron spectroscopy, electron spectroscopy, magnetism and DTA-TG. The D_q and B values were calculated. (12) The crystal and molecular structure of H_ (26) O_4N_2 complex are monoclinic with space group P2_1 / a, a = 7.512 (1) A, b = 8.524 ) A, β = 100.29 (1) A, V = 963.05A, Z = 2. The structure is solved by the Patterson method and the final deviation factor is R = 0.027. The Ni (Ⅱ) ion in the molecular structure coordinates with two nitrogen atoms and two oxygen atoms in the macrocyclic ligand and two nitrogen atoms in NCS- to form a six-coordinated distorted octahedron.
