Copper(I) alkynyl complexes have attracted tremendous attention in structural studies, as luminescent materials, and in catalysis, and homoleptic complexes have been reported to form polymers or large clusters. Herein, six unprecedented structures of Cu^I alkynyl complexes and a procedure to measure the cone angles of alkynyl ligands based on the crystal structures of these complexes are reported. An increase of the alkynyl cone angle in the complexes leads to a modulation of the structures from polymeric [((PhC≡CC≡C)Cu)₂(NH₃)]_∞, to a large cluster [(TripC≡CC≡C)Cu]₂₀(MeCN)₄, to a relatively small cluster [(TripC≡C)Cu]₈ (Trip=2,4,6‐iPr₃‐C₆H₂). The complexes exhibit yellow‐to‐red phosphorescence at ambient temperature in the solid state and the luminescence behavior of the Cu₂₀ cluster is sensitive to acetonitrile.

从簇到聚合物：配体锥角控制的合成和铜（I）炔基配合物的结构

铜（I）炔基配合物在结构研究，发光材料和催化方面引起了极大的关注，据报道均均配合物可形成聚合物或大簇。在此，报道了Cu ^I炔基络合物的六种前所未有的结构以及基于这些络合物的晶体结构测量炔基配体的锥角的方法。配合物中炔基锥角的增加导致结构从聚合物[[（（PhC≡CC≡C）Cu）₂（NH ₃）] _∞到大簇[[TripC≡CC≡C） Cu] ₂₀（MeCN）₄到相对较小的簇[（TripC≡C）Cu] ₈（Trip = 2,4,6‐ iPr _3‐ C ₆ H ₂）。配合物在环境温度下呈固态呈黄色至红色磷光，Cu ₂₀团簇的发光行为对乙腈敏感。
