Abstract
Using a polyamine cation tetrenH(5)(5+) (tetren = tetraethylenepentaamine), we tailored the dynamic layered material (tetrenH(5))(1.6)-{Co-II(H2O)(2)[M-IV(CN)(8)]}(4)center dot xH(2)O (1, M = W, x = 12; 2, M = Mo, x = 11.2). 1 and 2 consist of strongly corrugated two-dimensional (2D) cyanobridged monolayers {Co-II(H2O)(2)[M-IV(CN)(8)]}(n)(2n-) of square grid topology stacked in an alternate manner with cationic layers of tetrenH(5)(5+) and H2O molecules. The observed single-crystal-to-single-crystal (SCSC) transformation is due to the reversible dehydration of 1 and 2 to the respective monocrystalline materials (tetrenH(5))(1.6){Co-II[M-IV(CN)(8)]}(4) (1deh and 2deh). Structural modifications consist of the change of coordination number (C.N.) of Co(II) from 6 to 4 and a degree of corrugation of the coordination skeleton resulting in changes of orthorhombic cell dimensions. The exposition of 1deh to vapors of H2O, MeOH, HCONH2, and MeCN gives 1reh, 1deh center dot 5.6MeOH, 1deh center dot 4HCONH(2), and 1deh center dot 2.4 MeCN phases, respectively 1reh reveals structural, physical, and physicochemical characteristics of 1, while 1deh center dot guest: 1deh center dot 5.6MeOH, 1deh center dot 4HCONH(2), and 1deh center dot 2.4MeCN evidently follow features of 1deh. When exposed to humidity, 1deh center dot guest phases reabsorb H2O to give respective mixed 1deh center dot guest center dot H2O phases. Structural changes are followed by single crystal and powder X-ray diffraction, magnetic measurements and IR, UV-vis-NIR, and electron spin resonance (ESR) spectroscopies. The values of the effective crystallographic volume for interlayer guest molecules and tetrenH(5)(5+) are estimated and discussed. The solid state-gas phase reactivity of 1, 1deh, and 1deh center dot guest is interpreted in terms of competition between Co(II)-guest coordination bonding and noncovalent interactions between guest molecules and interstitial molecules.
