摘　　要：The title compound biaquo (1.12-diaza-3, 4 : 9 . 10-dibenzos-5, 8-dioxacyclopentadecane-N-acetate) copper nitrate dihydrate. [Cu (C21H25O4N2) ( H2O)2].NO3·2H2O, Mr= 567. 05 . has been prepared. It crystallizes in the monoclinic system. space group P21/a with a 12. 302(4) - b 13. 244(4), c= 15. 774(6)A . g=98. 59', V 2541 (l)\, Z 4. A(MoKα) = 0. 71069 A . D. l. 48 gcm-3. The structure was solved by direct methods with the final R 0. 060, R. 0. 081 for 3305observed reflections (I> 3a (I) ). The copper atom is surrounded by two nitrogen atoms and one oxygen atom from the carboxyl of the ligand and two oxygen atoms of coordinated water in a distorted square pyramidal arrangement. However, the two'ether oxygen atoms of the macrocyclic ligand are uncoordinated.The title compound biaquo (1.12-diaza-3, 4 : 9 . 10-dibenzos-5, 8-dioxacyclopentadecane-N-acetate) copper nitrate dihydrate.
