Abstract

Hydrolysis of the DMF or DEF solvent influences the nature of the product obsd. in the reaction between Zn(II) nitrate and 1,4-benzenedicarboxylic acid, with dialkylammonium cations able to template the formation of anionic networks. In fresh DEF [Zn4(micro 4-O)(micro -bdc)3].3DEF was prepd. whereas in DEF that had been in the lab. for several weeks, [NH2Et2]2[Zn3(micro -bdc)4].2.5DEF was prepd. When the reactions were carried out in DMF instead of DEF, similar observations were recorded. Use of a partially hydrolyzed sample of solvent, or addn. of [NH2Me2]Cl. led exclusively to [NH2Me2]2[Zn3(micro -bdc)4].DMF.H2O. The prepn. and characterization of compds. 1-3 demonstrate that solvent quality is crucially important in prepg. dicarboxylate-based coordination compds. [on SciFinder (R)]
