First aggregation of L-cysteinato cobalt(III) octahedrons assisted by trigonal-planar silver(I) and trigonal-prismatic sodium(I) ions
The reaction of Delta(L)-[Co(L-Hcys-N,S)(en)(2)](ClO4)(2) with NaOH and AgClO4 in a 2 : 2 : 1 ratio in water gave a 2 : 1 (Co:Ag) adduct, (Delta(L))(2)-[Ag{Co(L-cys-N, S)(en)(2)}(2)](3+) ((Delta(L))(2)[1](3+)), while the corresponding reaction with AgNO3 led to the isolation of a 3:1 adduct, (Delta(L))(3)-[AgNa{CO(L-cys-N,S)(en)(2)}(3)](5+) ((Delta(L))(3)-[2](5+)). The discrete trinuclear structure in (Delta(L))(2)-[1](3+) and the 2D polymeric structure in (Delta(L))(3)-[2](5+) were determined by X-ray crystallography.
