Reaction of lithium phenylselenothiolate, generated in situ from the reductive cleavage of PhSe‐SiMe 3 with alkyl lithium reagents and insertion of elemental sulfur, with triphenylphosphine solubilized CuCl affords the molecular cluster complex [Cu 20 Se 4 (μ 3 ‐SePh) 12 (PPh 3 ) 6 ] ( 1 ). The analogous reaction with AgCl yields the extended structure [Ag(SePh)] ∞ ( 2 ) in which an infinite layer of Ag I atoms is capped on either side by μ 4 ‐SePh ligands. 1: space group P¯1, a = 17.9510(6), b = 18.1712(7), c = 31.4311(11) Å, a = 78.098(2), β = 82.905(2), γ = 70.012(2)°. 2: space group C2/ c , a = 5.8762(6), b = 7.2989(7), c = 29.124(2) Å, β = 95.790(3)°.
