Phosphine-stabilized gold clusters are an important subgroup of metalloid gold cluster compounds and are important model compounds for nanoparticles. Although there are numerous gold clusters with different phosphine ligands, the effect of phosphine on cluster formation and structure remains unclear. While the linear alkyl-substituted phosphine gold chlorides result in a Au32 cluster, the bulky tBu3P leads to a Au20 cluster. The reduction of (iPr2nBuP)AuCl, with the steric demand of the phosphine ligand between the mentioned phosphines, results in the successful synthesis and crystallization of a new metalloid gold cluster, Au30(PiPr2nBu)12Cl6. Its structure is similar to the Au32 cluster but with two missing AuCl units. The UV/Vis studies and quantum chemical calculations show the similarities between the two clusters and the influence of the phosphine ligand in the synthesis of metalloid gold clusters.

The core expansion of metallic or metalloid clusters by the addition of further homo- or heteronuclear vertices is pivotal to the nucleation and growth of particles. The exohedral grafting of a low-valent functionality followed by endohedral incorporation have been identified as key steps. Following previous work on the Si6 series, we now report the synthesis and full characterization of the amidinatotetrylene-functionalized seven-vertex siliconoids Si7R5[E(N t Bu)2CPh] (E = Si, Ge, Sn). In the case of the silylene derivative, the solid-state structure was determined by single crystal X-ray diffraction.

A series of cyclopentadienyllanthanum complexes with the disilylated metalloid germanium cluster [Ge 9 (Hyp) 2 ] 2− [Hyp = Si(SiMe 3 ) 3 ] has been prepared and fully characterized. The synthetic procedure is based on the salt metathesis reaction of two different cyclopentadienyllanthanum diiodides CpLaI 2 (Cp: Cp*, pentamethylcyclopentadienyl; Cp ttt , 1,2,4-tri-tert-butylcyclopentadienyl) with K 2 [Ge 9 (Hyp) 2 ] in tetrahydrofuran (THF) with a subsequent extraction with n-hexane. The composition of the obtained compounds and the mode of coordination of the germanium cluster to the rare-earth metal are strongly influenced by the steric demand of the cyclopentadienyl ligands and the crystallization conditions. The centrosymmetric dimeric compounds with the common formula [CpLa(solv)(η 2,3 -Ge 9 (Hyp) 2 )] 2 [1, Cp = Cp*, solv− THF; 2, Cp = Cp ttt , solv−NCCH 2 C(Me)NSiMe 3 ] have been isolated by the slow evaporation of a n-hexane solution, while a mononuclear complex [Cp ttt La(THF) 2 (η 3 -Ge 9 (Hyp) 2 )] (4) was found by crystallization from THF. The repeated recrystallization of 1 from n-hexane afforded the asymmetric dimer [Cp*La(THF)(η 2,3 -Ge 9 (Hyp) 2 )][Cp*La(η 2,3 -Ge 9 (Hyp) 2 )] (3) with only one coordinated THF molecule.
