Abstract
The title complex, [Fe4(C5H7O2)4(CH3O)6Cl2] or [Fe4(acac)4(μ2-OMe)4(μ3-OMe)2Cl2] (acac = acetyl-acetonate), crystallizes in the ortho-rhom-bic Pbca space group with one half of the mol-ecule per asymmetric unit, the other half being completed by inversion symmetry. The core structure consists of a face-sharing double pseudo-cubane entity with two opposite corners missing. Weak C-H⋯Cl inter-molecular inter-actions result in a two-dimensional layered structure parallel to the ac plane.

Summary
Metal silanolate complexes bearing methoxy and ethoxy groups on silicon are relatively rare (Dupuy et al, 2012) in comparison to tert-butoxysilanolate complexes (McMullen et al, 1989, 1990; Nozaki et al, 2002; Terry et al, 1993, 1996; Truscott et al, 2013). NaOSi(OMe)2Me to a metal halide results in the formation of a methanolate complex instead of silanolate complex. In line with this observation, we report that the addition of.
