A "cation-less" oxalate-based ferromagnet formed by neutral bimetallic layers: {[Co(H2O)2]3[Cr(ox)3]2(18-crown-6)2}(infinity) (ox = oxalate dianion; 18-crown-6 = C12H24O6).
Neutral layers of the bimetallic oxalate complex {[Co(H2O)2]3[Cr(ox)3]2}infinity are formed in the presence of a crown ether and stabilized by hydrogen bonding. The resulting soluble ferromagnet orders at Tc = 7.4 K.
