N2 - A 2D coordination polymer [Zn(ATRZ)2(H2O)2](ATRZ)(CBH)2·2H2O, ( ZAC ) was constructed using 4,4′-azobis-1,2,4-triazole (ATRZ) as the linker, Zn2+ as the node, and active cyanoborohydride (CBH) as the dissociative anion. Its crystal structure and properties were characterized by X-ray diffraction (XRD), differential scanning calorimetry-thermogravimetry (DSC-TG), oxygen bomb calorimetry, and mechanical sensitivity measurements (X-ray density: 1.548 g·cm−3; thermal decomposition temperature, Td : 179.14 °C; specific energy, Eg : 15.76 kJ·g−1; energy density, Ev : 24.40 kJ·cm−3; impact sensitivity, IS: 30 J; friction sensitivity, FS: 288 N). ZAC is characterized by a unique 2D polymer stabilized by the coordination of Zn2+ with linker ATRZ and aqua ligands, while free ATRZ, CBH anion and crystal water are packed in the polymer. The combustion performance of ZAC /KClO4 ( ZACK ) composite was evaluated in detail (Heat of combustion: 5.25 kJ·g−1; peak pressure: 3.23 MPa; response time: 11.07 ms; linear burning rate: 124.6 mm·s−1). Improved performance relative to conventional BPN (B/KNO3) was observed, highlighting its potential for energetic materials applications.
