Abstract

Poly[bis(mu(3)-trimethylsilylmethanolato)tetrakis(mu(2)-trimethyl-silylmethyl)dimagnesiumdisodium], [Na2Mg2(C4H11OSi)(2)-(C4H11Si)(4)](n), was obtained from the controlled exposure to oxygen of the unsolvated sodium magnesate [NaMg(CH2-SiMe)(3)](n). Exhibiting a centrosymmetric (Z' = 1/2) dimeric core of a heterobimetallic eight-membered cationic ring, hosting two alkoxide ligands at its core, the title compound forms a two-dimensional coordination polymer in the crystallographic bc plane through Na center dot center dot center dot Me contacts. These contacts from Na to formally uncharged groups are only 0.06 angstrom longer than those between Na and the formally charged CH2R anions. The coordination polymers stack along the a direction to give a layer structure with alternating hydrophobic and hydrophilic regions.
