• First examples of the coordination chemistry of the As4S3 cage were obtained from solutions of As4S3·M(CO)5 (M = Cr, W) in CH2Cl2 and CuCln in CH3CN (n = 1) or CH3OH (n = 2) through interdiffusion techniques. The compounds (As4S3)(CuCl)n (1: n = 1; 2: n = 2) exhibit Cu coordination exclusively through the sulfur bridges. The crystal structure of 1 containsa saw‐like [CuCl] backbone to which As4S3 cages are alternately fixed on both sides through two of their sulfur atoms. The crystal structure of 2 is built up of sheets, in which As4S3 molecules are connected by folded four‐membered Cu2Cl2 rings through all sulfur atoms. Comparative Raman spectra of As4S3 and 1 indicate significant interactions between the cage S atoms and Cu.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009) First examples of the coordination chemistry of the As4S3 cage are reported. Compounds (As4S3)(CuCl)n, which form in interdiffusion experiments of solutions of As4S3·M(CO)5 in CH2Cl2 and CuCln in CH3CN (n = 1) or CH3OH (n = 2),represent first examples of the novel S‐only coordination mode of the intact E4S3 cage molecules (E = P, As).
