Abstract: Synthesis and molecular structures of two metallated (aluminium) derivatives, [C9H19Cl4AlN5O2P3]· 1.5C7H8 and [C8H16Cl5AiN5O2P3] · 1.5C7H8, of the macrocycle-bearingcyclophosphazene N3P3Cl4 [HN--- (CH2)3---O---(CH2)2---O---(CH2)3-NH] (coded as SPIRO 30203) are reported. These two molecular structures reveal the same pattern of metal coordination where the two hydrogen atoms in SPIRO 30203 are substituted by aluminium generating monomeric structures with pentacoordinated aluminium centres in the inner cavities. In the first compound the exocyclic ligand at aluminium is a methyl group, in the second a chlorine atom. Typical Al---N, Al---O and Al-X distances are (Å):1.84-1.89, 1.97-2.04 and 1.93 in the former, 1.81-1.86, 1.93-2.01 and 2.12 in the latter, respectively.
