The reaction of [ZnGe(Hyp)] (Hyp = Si(SiMe)) with Pt(PPh) gives the neutral polynuclear complex of Ge(Hyp) units [HypZn-Ge(Hyp)-Pt-Ge(Hyp)-ZnHyp], 1. Within 1, the central Pt atom is bound η to both Ge(Hyp) units to which further ZnHyp units are bound again, symmetric η, to the other side of the Ge(Hyp) units, leading to the longest chain compound exhibiting Ge(Hyp) units that is known to date. Dissolved crystals of 1 give a violet solution, showing an absorption maximum around 543 nm. Further UV-vis investigations on different M Ge(Hyp) compounds show that the absorption maximum depends on the number of transition metal atoms bound to the Ge(Hyp) unit, which is supported by TD-DFT calculations.
[ZnGe(Hyp)]（Hyp = Si(SiMe)）与 Pt(PPh)3反应生成中性多核配合物 Ge(Hyp)单元[HypZn-Ge(Hyp)-Pt-Ge(Hyp)-ZnHyp]，1。在 1 中，中心 Pt 原子η结合到两个 Ge(Hyp)单元，进一步的 ZnHyp 单元再次对称地η结合到 Ge(Hyp)单元的另一侧，导致最长链化合物显示出已知的 Ge(Hyp)单元。1 的溶解晶体给出紫色溶液，在大约 543nm 处显示出最大吸收。对不同 M Ge(Hyp)化合物的进一步 UV-vis 研究表明，吸收最大值取决于与 Ge(Hyp)单元结合的过渡金属原子的数量，这得到了 TD-DFT 计算的支持。
