AbstractThis article describes the structure determination of five homoleptic d10 metal-aryl/alkylacetylides [RC≡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≡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≡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≡C groups. Complex 3 forms an infinite chain structure with extended Cu-Cu ladders (Cu-Cu = 2.49(4)-2.83(2) Å). The silver(I) congener 4 is iso-structural to 3 (average Ag-Ag distance 3.11 Å), whereas the gold(I) analogue 5 forms a Au⋯Au honeycomb network with PhC≡C pillars (Au-Au = 2.98(1)-3.26(1) Å). Solid-state properties including photoluminescence, v(C≡C) stretching frequencies and thermal stability of these polymeric systems are discussed in the context of the determined structures. © 2005 Wiley-VCH Verlag GmbH & Co.
