Structure and properties of dibridged (mu-oxo) (mu-CO3) diiron (III) complex

A (mu -oxo) (mu -CO3) diiron (III) complex of tri (2-pyridylmethyl) amine ( TPA), [Fe2L2 (mu -O) (mu -CO3)] (ClO4)(2) . MeOH . EtOH . H2O], was synthes ized and characterized, where L represents TPA. This complex crystallizes i n 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, beta = 115. 393(3)degrees, 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 comp ound show multiply absorption bands in 200-800 nm range, which are similar to that of N-3(-) coordinated met-hemerythrin.
