Abstract

A metal-organic coordination polymer of the formula [Li3(btc)(H2O)] (1a) (H3btc is the trimesic acid, C6H3(COOH)3) was obtained upon heating a mixture of LiBH4 and H3btc in ethanol. The structure was established by single crystal X-ray diffraction study. The studies by TGA show that polymer 1a loses the coordinated water at T ≥ 250 °C, whereas the metal-organic framework of lithium trimesate disintegrates only above 500 °C. The luminescence spectra showed a considerable (5-fold) increase in luminescence intensity and a bathochromic shift upon dehydration of 1a.
