    The complex [Li(TMEDA)]Ni-2(CH(2)CMe(2)CMe(2)CH(2))(2) 1 was synthesized with good yield by treatment of NiCp(2) with the dilithium compound LiCH(2)CMe(2)CMe(2)CH(2)Li 2. It was characterized by elemental analysis, H-1 and C-13 NMR and X-ray spectroscopy. The crystal data and the final R values are as follows: crystal system: orthorhombic, space group Pnma (No. 62) with cell parameters a = 17.849(3) Angstrom b = 13.138(2) Angstrom c = 14.516(1) Angstrom Z = 4 and R = 0.062, R(w) = 0.060. The average distance Li-Ni (2.506(7) Angstrom) is only little larger than the sum of the covalence radii of the two elements (2.38 Angstrom). According to DTA studies, the following decomposition temperatures of the complexes 1, [Li(TMEDA)]Ni-2(CH2CH2CH2CH2)(2) 3, [LiL(2)]Ni-2(CH2CH2CH2CH2)(2) (L = THF 4, d(8)-THF 5) resulted: 1 (234 degrees C), 3 (182 degrees C), 4 (108 degrees C), 5 (108 degrees C). Surprisingly they vary considerably. After the DTA measurement, the gas phases above the solid decomposition residues were analyzed by gas chromatography and mass spectroscopy. The results of these investigations are reported.

    The X-ray investigation at the "ate-complex" [Li(TMEDA)](2)Pt(CH2CMe2CMe2CH2)(2) (1) revealed a new structure type of homoleptic organometallic compounds of platinum(II). Differences of the molecular structure of the "ate-complex" [Li(TMEDA)](2)Pt(CH2CH2CH2CH2)(2) (2) as well as similarities to the structure of the homologeous "ate-complex" of nickel(II) [Li(TMEDA)](2)Ni (CH2CMe2CMe2CH2)(2) (3) are described. A possible mechanism of the thermal decomposition of the complex 1 is discussed.
