Bis(S‐ethyl‐ethene‐1,2‐dithiolato)palladium(II), Pd(S 2 C 4 H 7 ) 2 , is monoclinic, P 2 1 /n, with a = 7.598(1) Å, b = 10.445(2) Å, c = 8.031(1) Å, β = 95.3(1)° and Z = 2. The structure was determined by 893 independent reflections and refined by the block‐diagonal leastsquares method to R = 0.12. The chelate molecule is nearly planar and the palladiumsulfur distances are 2.278(6) Å and 2.403(6) Å. Bis(S‐ethyl‐ethene‐1,2‐dithiolato)platinum(II), Pt(S 2 C 4 H 7 ) 2 , is monoclinic, P 2 1 /a, with a 13.114(2) Å, b = 12.873(2) Å, c = 7.446(2) Å, β = 96.1(1)° and Z = 4. The structure was solved from 2040 independent reflections. The compound is not isomorphic with the isomeric palladium complex. In the unit cell there exist two symmetry independent molecules. The platinum‐sulfur distance is 2.280 (6) Å.
