The thermal expansion behavior of a metal-formate framework, Zn(HCOO)₂·2(H₂O) (<b>1</b>), has been systematically studied via variable temperature single-crystal X-ray diffraction. Our results demonstrate that this formate exhibits significant negative thermal expansion (NTE, -26(2) MK<sup>-1</sup>) along its <i>c</i>-axis. Detailed structural analyses reveal that the large NTE response is attributed to the 'hinge-strut' like framework motion. In addition, the fundamental mechanical properties o ...[more]
