Abstract
The extractions of alloys of the nominal composition “KE2.25” with ethylenediamine (en), (2,2,2)crypt, and toluene (tol) lead in good yields to paramagnetic compounds of the composition [K‐(2,2,2‐crypt)]6E9E9 · 1.5 en · 0.5 tol (E = Sn (2 b), Pb (2 c)). X‐ray single crystal structure analyses show that two different E9 clusters per asymmetric unit are present with configurations of distorted tricapped trigonal prismatic polyhedra. 2 b: space group P21/c (No. 14), Z = 4, a = 28.042(8), b = 23.527(5), c = 27.703(8) Å, β = 93.46(2)°; 2 c: space group P21/c (No. 14), Z = 4, a = 28.356(8), b = 23.757(5), c = 27.885(8) Å, β = 94.01(2)°.
