摘要

A series of organically templated vanadium tellurites has been prepared under mild hydrothermal conditions. Single crystals were grown from mixtures of NaVO_3, Na_2TeO_3, and either 1,4-diaminobutane, 1,6-diaminohexane, or N,N,N′,N′-tetramethylethylenediamine in H _2O. Each compound contains similar [V_2Te_2O _(10)]_n 2n- layers. The layer metrics of [1,4-diaminobutaneH_2][V_2Te_2O_(10)], [1,6-diaminohexaneH_2][V_2Te_2O_(10)], [N,N,N′,N′-tetramethylethylenediamineH_2][V _2Te_2O_(10)], and [piperazineH_2][V _2Te_2O_(10)] reflect the steric bulk of the respective amines. Topotactic conversions between compounds through amine exchange are possible in reactions in which an increase in the strength of the amine-[V_2Te_2O_(10)]_n 2n- hydrogen-bonding network is observed.
