High polymers were formed from the reaction of Group IVB metallocene dichlorides and histamine.  The products were analyzed employing MALDI MS.  Low to moderate mass ion fragments to five units were identified.  Isotopic abundance matches are also reported.  The ion clusters contain intact segments along with multiple repeat units consistent with the proposed structure.  The loss of groups associated with the metal is common and emphasizes the instability of the metal moiety probably due to its reported instability in various mass spectral analyses.  There also exists a number of less intense ion fragment clusters within the studied range. Fragmentation generally occurs at heteroatom sites consistent with other studies.
