Abstract: For the first time, cocrystallization of two isomorphous silanethiolate complexes has been carried out. (Acetonitrile)bis(tri-tert-butoxysilanethiolato-²O,S)cobalt(II) and (acetonitrile)bis(tri-tert-butoxysilanethiolato-²O,S)zinc(II) gave orthorhombic monocrystals of their solid solution with a Co:Zn ratio refined to 0.81 (5):0.19 (5), viz. [Co(C₁₂H₂₇O₃SSi)₂(C₂H₃N)]_0.81[Zn(C₁₂H₂₇O₃SSi)₂(C₂H₃N)]_0.19. The product retained the structural characteristics of the substrates, viz. distorted trigonal-bipyramidal arrangement of ligands around the M^II atom and crystallographically imposed C₂ symmetry with the M-NCMe fragment lying on a twofold rotation axis.
