Abstract

Reaction of spermine with M(OiPr)4 (M = Ti, Zr) in toluene solution results in the formation of crystalline coordination polymers [M2(OiPr)8(C10H26N4)]. In these compounds, only the terminal primary amino groups are coordinated to the metal centers. The adducts are stabilized by intramolecular hydrogen bonds. NMR spectroscopy indicates that only the adduct with Zr(OiPr)4 is stable in benzene solution, whereas it dissociates in the case of Ti(OiPr)4. When dichloromethane was used as the solvent, spermine dihydrochloride crystallized from the solution.
