WebThe molecule adopts a structure similar to that of ethane, with which it is isoelectronic. The B−N distance is 1.58 (2) Å. The B−H and N−H distances are 1.15 and 0.96 Å, respectively. Its similarity to ethane is tenuous since ammonia borane is a solid and ethane is a gas: their melting points differing by 284 °C. WebMar 13, 2024 · As shown in Figure 2-4 (d), PCN-134 shows two peaks at 185.24 eV and 178.93 eV, corresponding to Zr 3d3/2 and Zr 3d5/2 [53] respectively, indicating the presence of Zr4+in the composite. These evidences are reasonable to show that PCN-134 and PCN-134 form heterojunction.
