3.3.1. MALDI MS spectral studies of molecular square grids Ni(lI) complexes For the unequivocal characterization of large molecules, mass spectrometry was found useful as complementary. The structure and stability of coordination complexes under ionization conditions are dependent on various factures like the ligand itself, metal ions, counter ions, solvent, temperature, concentration, etc. MALDI mass spectra in dichloromethane as DCTB mix on positive ion mode have been found useful to get excellent results for stable Ni(II) square grids of both thiocarbohydrazones and carbohydrazones. MALDI MS spectrum of compound 1 (Fig. 3.1) in dichloromethane shows the presence of three main peaks centered at m/z 495.0602, 991.1073 and 1981.2342. The peak centered at l98l.2342 is assigned as the molecular ion peak expected for [Ni4(HL')L'3]+ (calc. m/z 1981, Fig. 3.2), well agreement with the simulation. The base peak at m/z 495.0602 is assigned as [Ni(HL')]+ (calc. 495) and the other major ao- 1 ' 1 peak is assigned as [Ni2(HL')L']+ (calc. 991, Fig. 3.2). . so 991 497 495 0602 I“Y mo 495 1931 so-; 70i * 1< ‘ l 498499 __ 496 l 4° l\Iass!Cha.rge w._ 1 l,,.l,?9°. .. 30 20 | 104 1175 " 536 ass ‘"2 1181 1360 use 1601 1751 1&4? 1947 2059 41]) 600 800 1000 1200 1400 1600 1000 Z000 MasaIChu9o R. 0 ' 7'7" 1 1'] >1 - ; 1 - ~ | - - 1 | . .'. ‘ 1" xi li 1‘: x‘: ; r*' F1 ; ; - '1 v‘ '"*-'""—v—I:1'i"'i—T"*—*T*T ~r1-{"1-.""'r"r'1—{"r‘ Fig. 3.1.
