Title: catena-Poly[[diaquamanganese (II)]-di-{mu}-1,1,3,3-tetracyano-2-ethoxypropenido-{kappa}{sup 4}N{sup 1}:N{sup 3}]. 2}-(2-ethoxy-1,1,3,3-tetracyanopropenido) manganese(II) dihydrate.

The crystal structure of the title compound, [Mn(C{sub 9}H{sub 5}N{sub 4}O){sub 2}(H{sub 2}O){sub 2}], conventionally denoted Mn(EtO-TCA){sub 2}(H{sub 2}O){sub 2}, where EtO-TCA is 2-ethoxy-1,1,3,3-tetracyanopropenide, is described. The EtO-TCA anions bridge Mn{sup II} centers through one of the nitrile N atoms of each of their two dicyanomethanide groups, thus forming dibridged chains along ab. These chains are linked into two-dimensional sheets through hydrogen bonding. The seven-atom bridge, which results in a long Mn...Mn intrachain interaction [9.0044 (4) {angstrom}], as well as the large interchain separations [8.3288 (4) and 8.5220 (4) {angstrom}] prohibit long-range magnetic ordering down to temperatures as low as 1.55 K.
