| 摘 要： | <正> The title complex LaC11H22O14N3 (Mr = 559. 27) crystallizes in the monoclinic space group P21/c with a=14. 452(7) ,b=8. 260(2),c= 16. 641(8) A ,β= 90. 85(4)°, Z = 4, V=1986. 2(1) A3,Dc=1. 87g·cm-3, F(000) = 1112,μ(MoKa) = 22. 7cm-1. The final refinement converged with R=0. 036 and Rw = 0. 038 for 2996 observed independent reflectios. The average La-O(crown) bond length of 2. 683 A (2. 660-2. 701A)is shorter than that in La(NO3)3(15-C-5)(2. 694A).The distances between opposite O atoms (3. 47~4. 68A) indicate that the cavity of 16-C-5 in the complex is elliptic.

| Abstract: | The title complex LaC11H22O14N3 (Mr = 559. 27) crystallizes in the monoclinic space group P21/c with a=14. 452(7) ,b=8. 260(2),c= 16. 641(8) A ,β= 90. 85(4)°, Z = 4, V=1986. 2(1) A3,Dc=1. 87g·cm-3, F(000) = 1112,μ(MoKa) = 22. 7cm-1. The final refinement converged with R=0. 036 and Rw = 0. 038 for 2996 observed independent reflectios. The average La-O(crown) bond length of 2. 683 A (2. 660-2. 701A)is shorter than that in La(NO3)3(15-C-5)(2. 694A).The distances between opposite O atoms (3. 47~4. 68A) indicate that the cavity of 16-C-5 in the complex is elliptic. |
