The thermal expansion properties of a newly synthesized mixed metal mixed organic MOF has been studied by variable temperature single crystal X-ray diffraction. The rare area NTE and large PTE of the MOF have been rationalized by an “elevator-platform” mechanism induced by O–H⋯O hydrogen bonding connecting the 2D layers in the crystal structure.

混合金属混合有机MOF中的区域负热膨胀：由O–H⋯O氢键引起的“电梯平台”机制†

通过可变温度单晶X射线衍射研究了新合成的混合金属混合有机MOF的热膨胀特性。MOF的稀有区域NTE和大PTE已通过由O–H⋯O氢键连接晶体结构中2D层的“升降平台”机制进行了合理化处理。
