摘要：

The reaction of barium metal with Hthd in dry pentane results in the tetranuclear complex Ba4(thd)8 (I), which can be sublimed in vacuo. Using Hthd, containing a small amount of pivalic acid, the pentanuclear chelate Ba5(thd)9(piv) (II) was isolated. Crystal structure determination shows the rhomboid arrangement of barium atoms in I and square Ba4 units combined with Ba3 triangles in a common side in II. All thd ligands in I are monochelating and differ only by the number of additional O-Ba bonds. In structure II, besides this type of coordination, a new bichelating coordination mode of beta-diketonate ligands has been found.
