The alkaline earth metal complexes [(畏²-3,5-tBu₂dp)(渭-Mg)(畏¹:畏¹-3,5-tBu₂dp)]₂ (2), {[(畏²-3,5-tBu₂dp)(渭-畏²:畏⁵-3,5-tBu₂dp)(渭-畏²:畏¹-3,5-tBu₂dp)Ca]₂(渭-Ca)} (3), [Sr(3,5-tBu₂dp)₂]_m (4), [Ba(3,5-tBu₂dp)₂)]_n (5), and [畏¹-{H(3,5-tBu₂dp)}₂Ca(畏²-3,5-tBu₂dp)₂] (6), bearing bulky 1,2,4-diazaphospholide ligands [3,5-tBu₂dp]^{鈭?/sup> ([3,5-tBu₂dp]鈭?/sup> = 3,5-di-tert-butyl-1,2,4-diazaphospholide), were prepared. The structures of magnesium and calcium 1,2,4-diazaphospholide complexes represent homoleptic 1,2,4-diazaphospholide alkaline earth metal oligomers with a novel array of metal鈥搇igand binding modes.}
