The title complex T1[DB-30C-10]ClO4(Mr=840. 45) crystallizes in the monoclinic,space group P21/n with a=12. 383(3),b= 18. 785(6),c= 14. 081(2) A and B=100.56(2) , Z=4, V= 3220.0A,Dx=1.734g/cm3,F(000) = 1672. The final refinement converged with R=0. 045 and Rw=0.053 for 2218 observed independent reflections. Ten oxygen atoms coordinated to thallium (I) are arranged in a hexadecahe-dron with quasi-D2h symmetry. Bond lengths and angles in the complexed and free crown-ethers are essentially the same but their conformations are different. Four of the C-O-C-C angles in (DB-30C-10) change from trans in the free to gauche in the complex;the remaining torsion angles are of the same type in both forms.
