A novel zinc(II) complex with the ligand 2,2',2''-(1,4,7-triazanonane-1,4,7-triyl)triacetate (NOTA).

ABSTRACT: The zinc(II) complex with NOTA [2,2',2''-(1,4,7-triazanonane-1,4,7-triyl)triacetate] has previously been synthesized and studied in solution, but was not isolated. The corresponding title Zn(II) complex penta-sodium(I) bis-{[2,2',2''-(1,4,7-triazanonane-1,4,7-triyl)triacetato]zinc(II)} tris-(perchlorate) methanol solvate, Na(5)[Zn(C(12)H(18)N(3)O(6))](2)(ClO(4))(3)·CH(3)OH, was crystallized as a sodium perchlorate double salt in methano-l solution. The asymmetric unit contains two independent [Zn(NOTA)](-) complex anion entities, five sodium cations, three perchlorate anions and a methanol solvent mol-ecule. The two Zn(II) cations exhibit a distorted trigonal-prismatic N(3)O(3) coordination with a bifacial arrangement of the donor atoms. Neither the methanol solvent mol-ecule nor the perch
