Indrichan, M. Revenko, N. Gérbéléu, N. Vyrtosu, Yu. Simonov] The electron-impact mass spectra of coordination compounds of nickel(II) with the general formula NiL2, in which the radical anions [C6H5N -N-C(SR)=NR1]−, where R=CH3 and R′=H(I), R=CD3 and R′=H(II), R=C2H5 and R′=H(III), and R=CH3 and R′=C6H5(IV), serve as the ligands, have been studied. In the mass spectra of compounds I-IV the peaks of the molecular ions have the highest intensity among the organometallic fragments. The initial stage of the fragmentation of [M]+. is associated with the formation of the rearrangement ions [NiL + H]+, [NiL + C6H5]+, and [NiL + SR]+, ions, whose appearance becomes understood, if it is taken into account that the removal of one ligand is accompanied by the impairing of spins and the mass spectra of compounds I-IV is the presence of lines for the [NiL]+ ion in them. The dissociative ionization of compounds I-IV is strongly reminiscent of the behavior of ordinary complexes of metals with ligands of the nonradical type. The fragmentation scheme of the molecular ions under the effects of electron impact has been presented and discussed. Plenum Publishing Corporation, 1990 Indrichan K.
