| Abstract: | The reaction of N-benzesulfonyl-l-glutamic acid (Bs-glu) with Zn(CH3COO)2 · 2H2O or Co(CH3COO)2 · 4H2O in the presence of imidazole (Im) produced two novel complexes Zn(Im)2(Bs-glu)]n (1) and Co(Im)2(Bs-glu)]n (2). Both of the complexes exhibit similar one-dimensional structural motif and coordination environment. Bs-glu adopts the bis-monodentated coordination mode linking two adjacent metal ions. The complex 1 shows intense photoluminescence in the solid state. Magnetic measurements for 2 show that the exchange interaction of the two Co(II) ions is antiferromagnetic. |
