Abstract

In the interaction of the heterometallic complex [Li2Zn2(py)2(piv)6] (piv is the pivalate anion, py is pyridine) with 2,5-dibromoterephthalic acid (H2Br2-bdc) or 9,10-anthracenedicarboxylic acid (H2adc), two coordination polymers [Li(DMF)(HBr2-bdc)] (1) and (Me2NH2)[Zn(Hadc) (adc)]·DMF·H2O (2) are obtained. During the synthesis, the initial tetranuclear heterometallic fragment is completely fragmentated. When the same complex interacts with nitroterephthalic acid (H2NO2-bdc), a heterometallic metal-organic framework (Me2NH2)[LiZn(NO2- bdc)2]·DMF (3) is formed. Resulting coordination polymer 3 has a three-dimensional porous structure; binuclear heterometallic carboxylate moieties {LiZn(COO)3} act as secondary building blocks.
