N2 - The zincation of triisopropylsilylamine with dimethyl- and diethylzinc yields dimeric methylzinc (1) and ethylzinc triisopropylsilylamide (2). Complex 1 crystallizes in the monoclinic space group P21/n, 2 in P21/c. The reaction of dimethylzinc with adamantylamine gives [(THF)ZnMe][(AdNH2)ZnMe][μ-N(H)Ad]2 (3) which crystallizes in the monoclinic space group P21/n. All these compounds have central Zn2N2 cycles. Contrary to 1 and 2 with triply coordinated metal centers, the zinc atoms in 3 show a distorted tetrahedral coordination sphere due to the contact to the neutral coligands THF and adamantylamine.
