Abstract

Heteronuclear complexes of the type Ln'(x)Ln ''(1-x)[Co(CN)(6)]. nH(2)O have been synthesized for potential applications in solid oxide fuel cells. SmxEr1-xCo and SmxYb1-xCo complexes crystallize in the orthorhombic system, as do LaxSm1-xCo complexes for x= 0-0.6. A plot of the lattice parameters of the orthorhombic structures of the complexes as a function of r(eff)[= xr(Ln')+(1-x)r(Ln '')] shows linear behaviour similar to that observed for the LnCo complexes. For the decomposed products, perovskite-type Ln'(x)Ln ''1-xCoO3 oxides are obtained. The crystal structure of Ln'(x)Ln ''1-xCoO3 is orthorhombic for 0.1080<r(eff)/nm<0.1199 and hexagonal for r(eff)>0.1199 nm, while for r(eff)<0.1080nm no perovskite-type oxide was formed. We suggest that the orthorhombic distortion parameter is greater than ca. 0.267 for r(eff)<0.1080 nm and therefore no perovskite-type oxide is formed.
