The complex crystallizes from 1:1 DMSO–acetonitrile as an acetonitrile solvate. In the crystal, weak C—H...O and C—H...N hydrogen-bonding interactions between adjacent complexes and between the acetonitrile solvent and the complex consolidate the packing.

Calcium bis{[tris(trimethylsilyl)silyl]tellanide} · 4THF is obtained by metallation of [tris(trimethylsilyl)silyl]tellane using dimeric calcium bis[bis(trimethylsilyl)amide] in toluene, followed by recrystallisation from tetrahydrofuran. The compound is characterized by a remarkable highfield shift of the 125Te{1H}-NMR resonance (-2204 ppm vs. Me2Te). The X-ray structure determination (triclinic, P1; Z = 1; a = 1042.6(2), b = 995.7(2), c = 1379.6(3) pm; α = 90.06(2), β = 92.76(2), γ = 94,03(2)° at -100 °C) shows a distorted octahedral coordination sphere of the calcium atom (Ca-Te 319; Ca-O 236 and 241 pm). The two [tris(trimethylsilyl)silyl]-tellanide ligands are in a trans position; the angle Ca-Te-Si is widened to 129°.
