The ligand N , N ‐dimethyl( N ′‐trimethylsilyl)ethane‐1,2‐diamine (HL) was treated with ZnEt 2 in varying stoichiometric ratios to synthesize [EtZnL] 2 and [ZnL 2 ] complexes. Crystal data: [EtZnL] 2 , monoclinic, P 2 1 / n , a = 10.0149(5) Å, b = 8.0296(3) Å, c = 16.1689(8) Å, β = 91.715(2)°. [ZnL 2 ], monoclinic, P 2 1 / n , a = 8.8457(3) Å, b = 15.4249(6) Å, c = 16.0121(7) Å, β = 92.656(1)°. The former complex is an amido nitrogen bridged dimer with distorted tetrahedral stereochemistry of the zinc atom and the latter is a distorted tetrahedral monomer based on amide/amine chelation.
