N2 - The complexes [M{NC5H4C(SiMe3) 2-2}2] [M=Mg (1), Zn (2), Cd (3), or Hg (4)], accessible either by metallation of NC5H4{CH(SiMe3) 2}-2 (≡RH) [for (1), using MgBunBus], or from LiR(thf)n (thf=tetrahydrofuran) [for (2)-(4), using MCl 2], are mononuclear metal(II) alkyls in which the dative metal-nitrogen interactions progressively weaken and C-M-C angles become more open in the sequence (1)→(4) [<M-N>, <C-M-C>: 2.13 Å, 157°, (1); 2.30 Å, 164°, (2); 2.49 Å, 174°, (3); 2.78 Å, 180°, (4); corresponding mean M-C distances are 2.22; 2.07; 2.27; 2.16 Å].
