Fig. 4.4. MALDI MS spectrum of complex 10. Insets are calculated isotropic
distribution patterns of main peaks.
The spectrum of Cu(II) thiocarbohydrazone complex ll exhibits peaks
centered at m/z 831, 447, 385, etc. The peak at 447 corresponds to [Cu(HL3)]+ (calc.
446) and is in agreement with calculated isotropic distribution (Fig. 4.5). The base
peak at 385 is of the fiee ligand HZL3 and weaker peak at 831 is assigned as
[Cu(HL3)(H2L3)]+ (calc. 830), may be formed under MALDI conditions. The spectrum
of 12 shows m/z 447 as base peak, which corresponds to [Cu(HL3)]+ (calc. 446) and
the peak at 413 corresponds to [Cu(I-IL3)-SH]+ (calc. 414), both are in agreement with
calculated isotropic patterns. The spectrum of complex 12 with calculated isotropic
pattems are given in Fig. 4.6.
