Over the past two decades, high hydrogen content and favorable dehydrogenation conditions of multi-metallic amidoboranes have gained significant attention for their potential in storage. Among them, Al-based complex hydrides shown promise because polarizing power, light weight, abundant natural presence. In this work, we successfully synthesized novel tetrahedrally coordinated amidoboranes, namely, Li[Al(BH3NHCH2CH2NHBH3)2] Na(THF)[Al(BH3NHCH2CH2NHBH3)2], using BH3NH2CH2CH2NH2BH3 (EDAB) as a precursor. The structure Na(THF)[Al(BH3NHCH2CH2NHBH3)2] was determined through modeling based on synchrotron powder X-ray diffraction. Additionally, formation Al-N bond confirmed with IR spectra. is more stable air than Li[Al(BH3NHCH2CH2NHBH3)2]. Importantly, thermal gravimetric analysis mass spectroscopic characterization that both compounds release without presence ammonia, diborane, or ethylenediamine. Our work represents first example chelation coordination geometry, which provides an essential foundation understanding relationship terms synthesis, structure, properties.
