The advancement of aerospace propulsion requires the development of environmentally benign, high-performance solid hypergolic fuels. While hydride-containing compounds offer superior combustion properties, their instability has historically limited their use. This paper explores the synthesis and performance of an atomically precise copper hydride cluster, Cu11H3(5N-dpf)6(OAc)2 (denoted as Cu11H3 ). When combined with high-test peroxide (HTP), the cluster achieves a remarkable ignition delay (ID) of 16 ms and a specific impulse of 254 s. This research highlights the critical role of hydride-proton interactions in accelerating the ignition process. 1. Introduction
