Abstract
A new heterometallic molecular complex [Co2Gd(NO3)(piv)(6)(py)(2)] (1, piv = (-O2CBut), py = pyridine) was synthesized. Its reaction with terephthalic acid (H(2)bdc) in N,N-dimethylacetamide (DMA) results in metal-organic coordination polymer [{CoGd(dma)(2)}(2)(bdc)(5)]center dot 4DMA (2). The crystal structures of 1 and 2 were determined by single-crystal X-ray diffraction analysis. The structure of 2 has two types of channels (4x8 and 5x16 ) that are occupied by coordinated and guest DMA molecules.
