“…For the two isostructural chains in 3 and 4 , the bands at 1928 and 1875 cm −1 in 3 and 1948 and 1890 cm −1 in 4 are attributed to the μ,η 1,2 ‐CC bridging modes. Previous infrared and Raman spectroscopic studies also did not support the presence of two chemically different types of CC bonds in the solid‐state structure of [{PhCCCu} ∞ ] and [{PhCCAg} ∞ ] 31a,b. The higher energy band at 2052 cm −1 in 4 is ascribed to asymmetric CC stretching due to weak silver–acetylide interactions 31c.…”

This article describes the structure determination of five homoleptic d(10) metal-aryl/alkylacetylides [RC triple bond CM] (M=Cu, R=tBu 1, nPr 2, Ph 3; R=Ph, M=Ag 4; Au 5) by using X-ray single-crystal and powder diffraction. Complex 1.C6H6 reveals an unusual Cu20 catenane cluster structure that has various types of tBuC triple bond C-->Cu coordination modes. By using this single-crystal structure as a starting model for subsequent Rietveld refinement of X-ray powder diffraction data, the structure of the powder synthesized from CuI and tBuC triple bond CH was found to have the same structure as 1. Complex 2 has an extended sheet structure consisting of discrete zig-zag Cu4 subunits connected through bridging nPrC triple bond C groups. Complex 3 forms an infinite chain structure with extended Cu-Cu ladders (Cu-Cu=2.49(4)-2.83(2) A). The silver(I) congener 4 is iso-structural to 3 (average Ag-Ag distance 3.11 A), whereas the gold(I) analogue 5 forms a Au...Au honeycomb network with PhC triple bond C pillars (Au-Au=2.98(1)-3.26(1) A). Solid-state properties including photoluminescence, nu(C triple bond C) stretching frequencies and thermal stability of these polymeric systems are discussed in the context of the determined structures.

Facile acetylide transfer reactions take place between gold(I) complexes Au(C[triple bond]CAr)(PPh3) (Ar = C6H5 or C6H4Me-4) and a variety of representative inorganic and organometallic complexes MXL, (M = metal, X = halide, L, = supporting ligands) featuring metals from groups 8-11, to afford the corresponding metal-alkynyl complexes M(C[triple bond]CR)Ln in modest to good yield. Reaction products have been characterised by spectroscopic methods, and molecular structure determinations are reported for Fe(C[triple bond]CC6H4Me-4)(dppe)Cp, Ru(C[triple bond]CC6H4Me-4)(dppe)Cp*, Ru(C=CCsF,)(l2-O2)(PPh3)Cp*, Ir(C-CC6H4Me-4)(eta2-O2)(CO)(PPh3), Ni(C[triple bond]CC6H4Me-4)(PPh3)Cp and trans-Pt(C[triple bond]CAr)2L2 (Ar = C6H5, L = PPh3; Ar = C6H4Me-4, L = PPh3, PMe3).

“…Thus, this difference in the IR spectra of Cu 2 C 2 and NaCu 5 (C 2 ) 3 does not exclude a possible structural similarity between both compounds, but as there are also big differences in other ranges of the IR spectra, it is very unlikely that NaCu 5 (C 2 ) 3 represents are crystalline model compound for the unknown structure of Cu 2 C 2 . More similarities are found in the spectra of NaCu 5 (C 2 ) 3 and phenylethynylcopper(I) ( [18,19], see Table 3). For the later only a vague structural model has been given [27], but the general structural features are similar to those found in NaCu 5 (C 2 ) 3 , i.e.…”

By heating the red residue of the reaction of NaC 2 H and CuI in liquid ammonia at 463 K for 30 min in a dynamic vacuum orange polycrystalline NaCu 5 (C 2 ) 3 is obtained. The crystal structure was solved and refined from X-ray powder diffraction data (orthorhombic, Pnma, a ϭ 732.80 (2) pm, b ϭ 1099.63(4) pm, c ϭ 726.15(2) pm, Z ϭ 4, R B ϭ 0.030). It consists of a three-dimensional framework of Cu I and C 2 2Ϫ ions with small channels running parallel to [100] and [001]. The sodium ions reside at the inter-NaCu 5 (C 2 ) 3 : das erste Alkalimetallübergangsmetallacetylid mit einer dreidimensionalen Gerüststruktur Inhaltsübersicht. Durch 30-minütiges Erhitzen des roten Rückstands der Reaktion von NaC 2 H mit CuI in flüssigem Ammoniak auf 463 K in einem dynamischen Vakuum wird orangefarbenes polykristallines NaCu 5 (C 2 ) 3 erhalten. Die Kristallstruktur wurde auf Grundlage von Röntgenpulverbeugungsuntersuchungen gelöst und verfeinert (orthorhombisch, Pnma, a ϭ 732,80(2) pm, b ϭ 1099,63(4) pm, c ϭ 726,15(2) pm, Z ϭ 4, R B ϭ 0,030). Sie besteht aus einem dreidimensionalen Netzwerk von Cu I und C 2 2Ϫ -Ionen
