Porous silver(I) organometallic coordination polymer of triptycene, and the guest desorption and absorption

On the basis study of porous silver(l) complex of triptycene (tpty), [Ag-3(tpty)(3)(ClO4)(3)](toluene)(2) (1), its toluene desorbed complex (2) and absorbed complex (3) have been synthesized and confirmed by H-1 NMR spectra and X-ray powder diffraction. In complex 1, a 3D architecture with triptycene exhibits an unprecedented mu-eta(2)-eta(2) or mu-eta(2)-eta(2)-eta(1) coordination mode depending on the steric requirements of the network. The desorption and absorption of guest molecules occur in this complex accompanying the structure change. The potential study of these complexes for the rational control and synthesis of porous organometallic coordination network is discussed. (C) 2002 Elsevier Science B.V. All rights reserved.
