mu Oxido bis[(hexaethyldimethyl 2 2' bidipyrrinato)iron(III)] (1) crystallizes as a mixed dichloromethane/water solvate as black plates in the triclinic system space group P (1) over bar with a = 14 536(3), b = 16 194(3) c = 25 883(5) angstrom alpha = 98 89(3)degrees, beta = 91 28(3)degrees, gamma = 90 56(3)degrees and Z = 2 In the crystal structure two distinct solvates 1 CH(2)Cl(2) and 1 H(2)O are present in equal ratio In both cases the solvent is found in direct vicinity of the Fe-O-Fe subunit and is located within a binding pocket formed by the two helically distorted tetrapyrroles Whereas the dichloromethane molecule is oriented within this pocket as a dipole with the positive end pointing towards the oxygen atom of the Fe-O-Fe subunit, the water molecule forms a hydrogen bond with this site, supported by additional weak interactions with adjacent N-donor atoms
