## Abstract Abstract. Yttrium(III) chloride was the ultimate precursor of the crystalline compounds [Y{η^5^‐C~5~H~4~(CH(SiMe~3~)~2~)}~2~(μ‐Cl)~2~Li(THF)~2~] (1), [Y{(OC(Bu^t^))~2~CH}~2~{μ‐OC(Bu^t^)C(H)C(Bu^t^)O}]~2~ (2), [{Mg(CH~2~SiMe~3~)(μ‐CH~2~SiMe~3~)(THF)}~2~] (3) and [Mg(CH~2~SiMe~3~){(N(C~6~H~3~Pr^i^~2~‐2,6)C(Me))~2~CH}(THF)] (4). Thus, the precursors were: YCl~3~ + 2 Li[η^5^‐C~5~H~4~{CH(SiMe~3~)~2~}] for 1, [Y{N(SiMe~3~)~2~}~3~] + 3 [Bu^t^C(O)]~2~CH~2~ for 2, and YCl~3~ + 3 Mg(CH~2~SiMe~3~)Cl for 3; whereas 4 was obtained from 3 + 2 H[{N(C~6~H~3~Pr^i^~2~‐2,6)C(Me)}~2~CH]. The β‐diketiminatochromium(II) compound 7 was prepared from CrCl~2~ + 2 Li[{N(C~6~H~4~Et‐2)C(Me)}~2~CH] (6); the latter became available from the corresponding equally new β‐diketimine 5 and LiBu^n^. Each of the compounds 1–7 was well characterised, including for 1–4 and 7 by single‐crystal X‐ray diffraction.
