The novel coordinatively saturated cyclopentadienyl palladium complexes [PdLn(η5-C5H5)](HLn= thermotropic 4-R,4′-R′-azobenzene; n= 1, R = R′= C6H13; n= 2, R = R′= C6H13O; n= 3, R = C6H13O, R′= C8H17OC6H4CO2; n= 4, R = C10H21O, R′= C8H17OC6H4CO2) are dark red solids which melt into isotropic fluids for n= 1,2, whereas for n= 3,4 liquid crystalline properties are exhibited with a stabilization of melting and clearing temperatures as high as 70 °C.
