摘要

This article reports synthesis, design, and luminescent properties of a series of structurally interesting coordination frameworks prepared from a modified purine ligand, 3-(2-amino-9H-purin-9-yl) propanoic acid (L). Corresponding transition metal complexes reported in this study were unambiguously characterized by X-ray crystallography to reveal an array of diverse crystallographic signatures reflecting crystal design around varying coordination geometries of a central metal ion. While silver complex 1 [C_(16)H_(18)Ag_2N_(10)O_5] affords formation of coordination framework with embedded dimeric, tetrameric, and pentameric metallacycles, corresponding copper complexation results in a discrete dimer 2 [C_(32)H_(46)Cl_2Cu_2N_(20)O_(14)]. Changing the counteranion from strongly coordinating chloride ion to weakly coordinating perchlorate anion resulted in the formation of a 1D coordination polymer 3 [C_(18)H_(26)Cl_2CuN_(10)O_(14)]. Cobalt complexes 4 [C_(16)H_(32)CoN_(10)O_(12)] and 5 [C_(16)H_(30)CoN_(12)O_(16)] yielded 2D grid-type assembly and a discrete dimer, respectively. Change in pH offered an interesting effect on the structural outcome of cadmium complexes:acidic and neutral conditions lead to the formation of 1D coordination polymer 6 [C_8H_(12)CdCl_2N_6O_6] and 7 [C_(16)H_(24)Cd_2N_(12)O_(14)], while basic conditions yielded an unusual porous metal organic framework 8 [C_9H_(15)CdN_5O_(5.5)].
