Beschreibung:
<jats:p>On the basis of the bis(4‐methylbenzoxazol‐2‐yl)methanide ligand three new alkali or alkaline earth metal compounds were synthesized, and their solid‐state structures are discussed in detail. On the way to new alkaline earth metal species a promising potassium precursor complex [K{(4‐MeNCOC<jats:sub>6</jats:sub>H<jats:sub>3</jats:sub>)<jats:sub>2</jats:sub>CH}{η<jats:sup>5</jats:sup>‐K(4‐MeNCOC<jats:sub>6</jats:sub>H<jats:sub>3</jats:sub>)<jats:sub>2</jats:sub>CH}(THF)]<jats:sub>∞</jats:sub> (<jats:bold>2</jats:bold>) and a homoleptic magnesium [Mg{(4‐MeNCOC<jats:sub>6</jats:sub>H<jats:sub>3</jats:sub>)<jats:sub>2</jats:sub>CH}<jats:sub>2</jats:sub>] (<jats:bold>3</jats:bold>) and calcium complex [Ca{(4‐MeNCOC<jats:sub>6</jats:sub>H<jats:sub>3</jats:sub>)<jats:sub>2</jats:sub>CH}<jats:sub>2</jats:sub>(THF)<jats:sub>2</jats:sub>]<jats:bold>·</jats:bold>THF (<jats:bold>4</jats:bold>) were obtained.</jats:p>
