摘要

Two new cyano-bridged Ru-Cu polymers, the one-dimensional chain {[Cu(tnH(+))(2)(H2O)(2)][Ru(CN)(6)]center dot 2H(2)O}(infinity) (1) (where to =.1,3-diaminopropane) and the pseudo-two-dimensional network {[Cu(tnH(+))(2)][Ru(CN)(6)]}(infinity) (2), have been prepared and fully characterized. Compounds 1 and 2 both crystallize in the same monoclinic space group, P2(1). Complex 1 was characterized by single crystal X-ray analysis, and compound 2 was characterized by X-ray powder diffraction (XRPD) techniques. Compound 2 was prepared by dehydration of 1; structure 1 can be regenerated by rehydration of 2. The "sponge-like" behavior of this molecular transformation is accompanied by a color change and has been shown by in situ X-ray powder diffraction and immersion calorimetry to be completely reversible.
