Article abstract of DOI:10.1039/DT9910002471

Reaction of sodium hydride in thf (thf = tetrahydrofuran) with H2salphen or H2salen gave the corresponding sodium derivatives Na2(salphen)(thf)n and Na2(salen)(thf)n.Recrystallization from 1,2-dimethoxyethane (dme) gave the stable solvated forms 1 and 2.From the X-ray analysis both have very similar structures with a cubane skeleton of alternate sodium and oxygen atoms.Crystallographic details: complex 1, space group P2₁/c, a = 12.045(1), b = 25.851(2), c = 16.467(1) Angstroem, α = γ = 90 deg, β = 107.61(1) deg, Z = 4 and R = 0.079 for 2118 independent observed reflections; 2, space group P2₁/n, a = 20.493(2), b = 21.682(2), c = 20.538(2) Angstroem, α = 90 deg, β = 110.53(1) deg, Z = 8 and R = 0.071 for 5054 independent observed reflections.
