Treatment of Li[BH3ER] (E=Se or Te, R=Ph; E=S, R=CH2Ph) with [Cp*CoCl]2 led to the formation of hydridoborate complexes, [{CoCp*Ph}{Cp*Co}{μ‐EPh}{μκ2‐E,H‐EBH3}], 1a and 1 b (1 a: E=Se; 1 b: E=Te) and a bis‐hydridoborate species [Cp*Co{μκ2‐Se,H‐SeBH3}]2, 2. All the complexes, 1 a, 1 b and 2 are stabilized by β‐agostic type interaction in which 1 b represents a novel bimetallic borate complex with a rare B−Te bond. QTAIM analysis furnished direct proof for the existence of a shared and dative B‐chalcogen and Co‐chalcogen interactions, respectively. In parallel to the formation of the hydridoborate complexes, the reactions also yielded tetracyclic species, [Cp*Co{κ3‐E,H,H‐E(BH2)2‐C5Me5H3}], 3 a and 3 b (3 a: E=Se and 3 b: E=S), wherein the bridgehead boron atoms are surrounded by one chalcogen, one cobalt and two carbon atoms of a cyclopentane ring. Molecules 3 a and 3 b are best described as the structural mimic of tetracyclo[4.3.0.02,4.03,5]nonane having identical structure and similar valence electron counts.

硫属元素稳定的钴双氢硼酸盐配合物:四环[4.3.0.02,4.03,5]壬烷的类似物。

用[Cp * CoCl] 2处理Li [BH 3 ER](E = Se或Te,R = Ph; E = S,R = CH 2 Ph)导致氢硼酸盐络合物[{CoCp * Ph} {的Cp *钴} { μ -EPh} { μ - κ 2 -E,H-EBH 3 }],1A1b中1:E =硒;图1b:E = Te)的和双-化硼酸盐物种的[Cp *钴{ μ - κ 2 -Se,H-SeBH 3 }] 22。所有复合物1 a1 b2通过β-声波型相互作用稳定,其中1b代表具有罕见的B-Te键的新型双金属硼酸盐配合物。QTAIM分析直接证明了存在共同的和固定的B-硫族元素和Co-硫族元素之间的相互作用。在平行于化硼酸盐复合物的形成,反应也产生四环物种,混合[Cp *钴{ κ 3 -E,H,H-E(BH 22 -C 55 ħ 3 }],33 b3 a:E = Se和3 b:E = S),其中桥头硼原子被环戊烷环的一个硫族元素,一个钴和两个碳原子包围。分子3a3b最好描述为具有相同结构和相似价电子数的四环[4.3.0.0 2,4 .0 3,5 ]壬烷的结构模拟物。
