The geometric configurations, electronic structures and polymerization thermodynamic properties of (Cl2AlNH2)n and (H2AlNH2)n(n=1～5) are investigated using HF/631G and B3LYP/631G methods, and the chemical bond strength of the two kinds of compound series are compared , and the reason of forming plane skeleton for AlnNn is analyzed. The results show that Cl2AlNH2 and H2AlNH2 molecules are of plane configuration C2 (EC), and their Al－N bond is a double bond which consists of a σtype bond and a  type bond(Cl2AlNH2)n and (H2AlNH2)n(n=1～5) molecules are of Dnh symmetry, and their Al－N bond representsσtype single bond. The stability order of (Cl2AlNH2)n and (H2AlNH2)n molecules are 3 > 2 > 4 > 5 > 1 and 8 > 7 > 9 > 10 > 6,respectively.
