文摘

From a hydrothermal reaction using CuI, KI, and 3,3鈥?,5鈥?tetramethyl-4,4鈥?bipyrazole (TMBP), the triiodide anion I₃^{鈥?/sup> has been integrated into the water-stable 2D coordination polymer Cu(TMBP)I₃ (1). In contrast with other metal triiodide complexes, 1 features remarkably small distortions in the bond distances associated with the I₃鈥?/sup> units (i.e., the Cu鈥揑 and I鈥揑 bonds), which effectively link up the copper(I) centers into infinite CuI₃ chains. The electronic band gaps and electrical conductivity data are also found to be consistent with the I₃鈥?/sup> ion acting as an effective linker across the copper(I) centers.}
