The peaks of complex 22 are seen centered at m/z 979.2559, 894.2743,
824.0774, 809.1023, 671.1977, 574.0566, 559.0818, 474.0995, etc. These
characteristic peaks are assigned as [Mn2(HL5)L5- CH3OH]+ (calc. 979),
[Mn(H2L5)HL5]+ (calc. 894), [Mn(HL5)(di-2-benzoylpyridine hydrazone)]+ (calc.
671), [Mn(H2L5)ClO4]+ (calc. 574), [Mn(H2L5-O)ClO4]+ (calc. 558) and base peak
[Mn(HL5)]+ (calc. 474) with well agreeing calculated isotropic pattems (Fig. 5.6). The
Mn(II) complex 23 exhibits many peaks, but none of the peaks match well with
simulation because of the absence of isotropic patterns, may be due to absence of
enough concentrated solution for measurement under the investigation condition or
due to extensive fragmentation along with coordination with DCTB under ionization
condition.
