The mononuclear complex Pd(1-TosC-N3)(2)Cl(2) (2) containing 1-(p-toluenesulfonyl)cytosine (1) as a ligand, as well as dinuclear complexes Pd(2)(1-TosC(-)-N3,N4)(4) (3) and Pd(2)(1-TosC(-)-N3,N4)(2)DMSO(2)Cl(2) (4) containing the ligand anion (1-TosC(-)), was mass analyzed by electrospray ionization ion trap MS/MS and high resolution MS. Complexes 3 and 4 were obtained by recrystallization of 2 from DMF and DMSO, respectively. The behavior of complex 2 in different solutions was monitored by electrospray ionization mass spectrometry (ESI-MS). Under the applied ESI-MS conditions, complex 2 in methanol reorganized itself dominantly as new complex 3 and the solvent did not coordinate the formed species. In H(2)O/DMSO, CH(3)CN/DMSO and CH(3)OH/DMSO solutions, complex 2 formed several new species with solvent molecules involved in their structure, e.g. complex 4 was formed as the major product. The newly formed species were also examined by LC-MS-DAD, confirming the solvent induced reorganization and the solution instability of complex 2.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
