Employing high-dilute method and 5-fold excess amine prepared two new "two-armed" acyclic diamine intermediates I_a and I_b, which are also intermediates of synthesizing microcyclic compounds, and eight aromatic Schiff bases, II_, were synthesized from reaction of I_a or I_b condensing with different aromatic aldehydes. Their composition and structure were characterized by Elemental analysis, IR, UV-Vis, LIF,~1HNMR and MS. The hydrogen bond interactions and MS fragmental patterns were also discussed.3. Several novel transition metal complexes using II_a as ligand were synthesized and identified by Elemental analysis, IR, UV-Vis,~1HNMR and molar conductivity.
