Two hourglass-type molybdophosphate hybrids with the formulas [Cd(HO)DABT][Cd(HPMoO)]·19HO () and (CHOH)(CHN)[Co(HPMoO)]·HO () (DABT= 3,3'-diamino-5,5'-bis(1H-1,2,4-triazole)) have been successfully designed and synthesized via a hydrothermal method. Structure analysis revealed that the inorganic moieties in compounds and are made up of hourglass-type {M[PMo]} (M = Cd/Co) structure, which were constructed by two (PMo) units with single transition metal (TM) (Cd/Co) atom as the central metal. The {M[PMo]} (M = Cd/Co) structures were then further connected by TM to constitute a 2D layered structure. Surprisingly, under the condition of 60 °C and 98% RH, compounds and exhibited excellent proton conductivity of 1.35 × 10 and 3.78 × 10 S cm, respectively. Furthermore, compound can act as heterogeneous catalyst for CO photoreduction, which indicates that it may be a bifunctional POM-based material with great promise.
通过水热法成功设计并合成了两种分子式分别为[Cd(HO)DABT][Cd(HPMoO)]·19HO ()和(CHOH)(CHN)[Co(HPMoO)]·HO ()的沙漏型钼磷酸盐杂化物（DABT = 3,3'-二氨基-5,5'-双(1H-1,2,4-三唑)）。结构分析表明，化合物 和 中的无机部分由沙漏型{M[PMo]}（M = Cd/Co）结构组成，该结构由两个(PMo)单元与单个过渡金属（TM）（Cd/Co）原子作为中心金属构建而成。{M[PMo]}（M = Cd/Co）结构随后通过TM进一步连接以构成二维层状结构。令人惊讶的是，在60°C和98%相对湿度的条件下，化合物 和 分别表现出1.35×10 和3.78×10 S cm的优异质子传导率。此外，化合物 可作为CO光还原的多相催化剂，这表明它可能是一种极具潜力的双功能基于多金属氧酸盐的材料。
