双碱稳定的二硼烷(4)[HB(1，3，4，6，7，8-hexahydro-2H-pyrimido[1，2-a]pyrimidinate)-μ)]2(hpp=Hpp)被用作二烷基锌配合物的第一个验证实例和以中性氢化硼为配体的卤化锌配合物的第二个实例中的配体。对三个配合物[ZnCl2{Hb(μ-hpp)}2](2)、[ZnBr2{Hb(μ-hpp)}2](3)和[ZnMe2{Hb(μ-hpp)}2](4)进行了充分表征。对粘接性能进行了详细的分析。这一分析表明，[Hb(μ-hpp)]2配体的两个氢原子和两个硼原子之间存在复杂的成键情况。
The doubly base-stabilized diborane(4) [HB(μ-hpp)]2 (hpp = 1,3,4,6,7,8-hexahydro-2H-pyrimido[1,2-a]pyrimidinate) was used as a ligand in the first authenticated example of a dialkylzinc complex and the second example of a zinc halide complex featuring a neutral boron hydride as ligand. The three complexes [ZnCl2{HB(μ-hpp)}2] (2), [ZnBr2{HB(μ-hpp)}2] (3), and [ZnMe2{HB(μ-hpp)}2] (4) were fully characterized. The bonding properties were analysed in detail. This analysis indicated a complex bonding situation involving not only the two hydrogen atoms, but also the two boron atoms of the [HB(μ-hpp)]2 ligand.
