| 抄録: | 1, 2, 4-Triazole (trz) is a heterocyclic base with high proton affinity, making it an excellent candidate as a hopping site for fast proton transport. In this study, we synthesized two paddlewheel-type dinuclear platinum complexes: (Htrz)₂[Pt₂(sq)₄(trz)₂]·3(H₂O) (1) and (Bu₄N)₂[Pt₂(sq)₄(trz)₂]·3(H₂O) (2), where H₂sq is squaric acid. Crystallographic study revealed that, in contrast to complex 2, complex 1 is the first example of an integration involving an N-H···N hydrogen-bonding interaction between neutral and protonated trz in the solid. Complex 1 exhibited a high proton conductivity of 1.0 × 10⁻⁴ S cm⁻¹ at 25 °C and 98% relative humidity, which was significantly higher than that of 2 (8.5 × 10⁻⁸ S cm⁻¹ under the same conditions). Infinite hydrogen-bonding networks, including trz-Htrz⁺ pairs, were apparently responsible for the high proton conduction observed in complex 1. |
