Borates with extended structures and interpenetrating system built from different types of cluster units are extremely rare. In this paper, we report a novel mixed‐alkali‐metal borate Na 3 Li 2 [B 4 O 7 ][B 5 O 8 (OH) 2 ] ( 1 ) synthesized under solvothermal conditions, showing a three‐dimensional twofold interpenetrating system constructed from two types of oxoboron clusters (B 4 O 9 and B 5 O 10 (OH) 2 ) setting as the first example in borates. And 1 also features an intricate 3‐D Li‐O−Na cationic network. In this work, we made a detailed comparison with other reported borates from 1‐D chain, 2‐D layer to 3‐D framework containing B 4 and B 5 clusters and further demonstrated that such 3‐D framework of 1 can be achieved by controlling the alkalinity of solution to prompt the concentration of two different oxoboron clusters with rich terminal hydroxyl groups together. Indeed, it can be regarded as a good interpretation of hydrolysis‐condensation processes in dimensional transformation of borates making it possible for the rational design of various structural borates in the future. Moreover, 1 displays fluorescence emission around 472 nm, making it an appropriate candidate for optoelectronic applications.
