Synthesis and X-ray single crystal structure analysis of an inorganic nucleoside analog

The inorganic nucleoside analog [Boc-aeg{Cu(pda)py-Ac}-OMe] (3) is prepared and fully characterized. The X-ray single crystal analysis reveals that 3 assembles by apical Cu–O bonds into a coordination polymer, with short Cu–Cu distances of 5.32 and 5.78 Å. The solid state structure of 3 is in accordance with an isotactic structural model for charge neutral inorganic nucleic acids analogs. Aeg = (2-aminoethyl)glycine, py-Ac = 4-acetyl pyridine, pda = pyridine-2,6-dicarboxylic acid.
