The molecular structure of aluminium and iron(III) complexes with 3-phenyl and 3-(4-pyridyl) (HL) substituted acetylacetonate ligands is appreciably distorted. For AlL3 and FeL3 this shows that the orientation of the side pyridyl-N donor atoms lone pairs is about 90 and 135° which favours the assembly of heterobimetallic square patterns in Al(Fe)L3 complexes with metal ions. This was employed for the modular construction of semi-regular heterobimetallic networks, in which the pyridyldiketonate ligands bridge pairs of Fe(Al)/Cd(Co) metal ions and support the structure of 1D and 2D coordination polymers. The unprecedented 2D structure of [Cd{AlL3}(CH3OH){NO3} 2]·2CHCl3 and Cd{AlL3}-(CH 3OH)Br2]·2CHCl3·2CH 3OH is based upon plane tiling by a set of heterobimetallic squares and octagons, while [Cd{FeL3}2(NO3) 2]·2H2O and [Co{AlL3}2Cl 2]·4CHCl3·2CH3OH are 1D polymers and exist as chains of heterobimetallic squares sharing opposite vertices.
