report the synthesis and structural characterization of Ga-substituted diarsene [L(EtO)GaAs]2, which is an exemplary case of a Ga-substituted dipnictene of the general type [L(X)Ga]2E2 (L = C[C(Me)N(2,6-i-Pr2-C6H3)]2, X = F, Cl, Br, I, NMe2, OEt; E = As, Sb, Bi). We examined this extended series of compounds computationally and found that attractive London dispersion interactions between the substituents
我们报告了Ga取代的二砷[L(EtO)GaAs] 2的合成和结构表征,这是一般类型的[L(X)Ga] 2 E 2(L = C [C(Me)N(2,6 - i- Pr 2 -C 6 H 3)] 2,X = F,Cl,Br,I,NMe 2,OEt; E = As,Sb,Bi)。我们通过计算检查了这一扩展的化合物系列,发现N,N'-螯合的β-二酮配体上的取代基之间的吸引人的伦敦分散相互作用以及第15组金属中心与配体之间的光子-π相互作用是产生这种现象的关键因素这类配合物的稳定性和电子结构。
