A ( μ oxo)( μ CO 3)diiron(Ⅲ) complex of tri(2 pyridylmethyl)amine(TPA), [Fe 2L 2( μ O) ( μ CO 3)] (ClO 4) 2·MeOH·EtOH·H 2O], was synthesized and characterized, where L represents TPA. This complex crystallizes in the monoclinic space group P2 1/c with a =1.181 0(3) nm, b =3.728 1(8) nm, c = 1.377 0(3) nm , β =115.393(3)°, V =5.477(2) nm 3, Z =4. R 1=0.084 9 and wR 2=0.196 2. The UV Vis spectra of this compound show multiply absorption bands in 200-800 nm range, which are similar to that of N - 3 coordinated met hemerythrin. , was synthesized and characterized, where L represents TPA.
