AB The zinc(II) complex with NOTA [2,20,200-(1,4,7-triazanonane1,4,7-triyl)triacetate] has previously been synthesized andstudied in solution, but was not isolated. The correspondingtitle ZnII complex pentasodium(I) bis{[2,20,200-(1,4,7-triazanonane-1,4,7-triyl)triacetato]zinc(II)} tris(perchlorate) methanolsolvate, Na5[Zn(C12H18N3O6)]2(ClO4)3 CH3OH, was crystallized as a sodium perchlorate double salt in methanol solution.The asymmetric unit contains two independent [Zn(NOTA)]complex anion entities, five sodium cations, three perchlorateanions and a methanol solvent molecule. The two ZnII cationsexhibit a distorted trigonal-prismatic N3O3 coordination witha bifacial arrangement of the donor atoms. Neither themethanol solvent molecule nor the perchlorate anions appearto be coordinated to the Zn centres. The crystal structureshows a layer arrangement parallel to (001) generated byinteractions between the [Zn(NOTA)] units, the Na+ cations,two ClO4 units and the methanole molecule, leading to anoverall layer composition of [Na5[Zn(C12H18N3O6)]2(ClO4)2.-CH3OH]+. The third ClO4 anion is isolated and situatedbetween the layers without any significant interactions PB Int Union Crystallography SN 2056-5368 YR 2009 FD 2009 LK http://hdl.handle.net/10347/23120 UL http://hdl.handle.net/10347/23120 LA eng NO Pereira García, Iria ; Macías, Alejandro ; Bastida, Rufina ; Valencia, Valencia.
