## Abstract Three isomeric zinc bisporphyrins have been prepared by covalently linking together two aminoporphyrins with an isophthalic acid derivative. The porphyrins differ in the substitution pattern on the __meso__ phenyl groups, that is, __ortho__, __meta__, or __para__. Titrations carried out
## Abstract The metalβorganic frameworks (MOF) of cluster [Cu~4~I~4~(DABCO)~2~] (DABCO=1,4βdiazabicyclo[2.2.2]octane) have been prepared and characterized as two different crystalline forms, **I** and **II**. Form **I** is obtained by reaction of DABCO and CuI in aqueous solution or by solvothermal
