摘要
Two new volatile mixed ligand barium complexes have been synthesized and their X-ray crystal structures determined. Ba-2(thd)(4)(bipy)(2) (1) consists of dimeric molecules; with two barium atoms linked by four bridging Ba-O-Ba bonds. The structure of ([Ba-7(piv)(12)(thd)(2)(py)(4)](H2O).2py) (2) contains Ba-3 units and separate Ba atoms which are connected into infinite chains through Ba-O-Ba bridges.
