Bulky alkylzinc complexes, (TtztBu,Me)ZnMe and (TtztBu,Me)ZnEt, show remarkable stability towards water and both complexes crystallize with one molecule of adventitious water hydrogen bonded to two triazole rings; in contrast the less bulky complex, (TtzPh,Me)ZnEt, reacts with water to yield (TtzPh,Me)2Zn.
