A two-step route to a range of fully N-alkylated azamacrocycles has been developed; the crystalstructure of trans-[Ni(L1)(NCS)2](L1= 1,4,8,11-tetrapropyl-1,4,8,11-tetraazacyclotetradecane) shows the nickel(II) to be six-coordinate, but with the uncommon (R,S,R,S)-or trans-(I)-set of N-configurations.
