摘要：

Studies of the growth of BaCO3 by using the evaporative transport of Ba(thd)2 (thd = 2,2,6.6-tetramethylheptane-3,5-dionate) in triethylamine (NEt3) are reported. The novel ionic compound [Ba6(thd)10(H2O)4(OH)2O2][HNEt3]2 (I) has been isolated from solutions used in this work. Characterization of 1, by X-ray single-crystal diffraction, shows that the molecule comprises an anionic hexameric cluster of Ba, thd, water and hydroxide ions centred on a bridging peroxide with charge balancing [HNEt3]+ cations in the lattice.
