While metal–oxygen clusters are widely used as secondary building units in the construction of coordination polymers or metal–organic frameworks, multimetallic nodes with heavier chalcogenide atoms (S, Se, and Te) are comparatively untapped. The lower electronegativity of heavy chalcogenides means that transition metal clusters of these elements generally exhibit enhanced coupling, delocalization, and redox-flexibility. Leveraging these features in coordination polymers provides these materials with extraordinary properties in catalysis, conductivity, magnetism, and photoactivity. In this perspective, we summarize common transition metal heavy chalcogenide building blocks including polynuclear metal nodes with organothiolate/selenolate or anionic heavy chalcogenide atoms. Based on recent discoveries, we also outline potential challenges and opportunities for applications in this field.

作为配位聚合物节点的重硫族化物-过渡金属簇

虽然金属-氧簇广泛用作配位聚合物或金属-有机框架结构中的二级结构单元，但具有较重硫族化物原子（S、Se和Te）的多金属节点相对尚未开发。重硫族化物的较低电负性意味着这些元素的过渡金属簇通常表现出增强的耦合、离域和氧化还原灵活性。利用配位聚合物的这些特性，使这些材料在催化、导电、磁性和光活性方面具有非凡的性能。从这个角度来看，我们总结了常见的过渡金属重硫属化物构建块，包括具有有机硫醇盐/硒化物或阴离子重硫属化物原子的多核金属节点。根据最近的发现，我们还概述了该领域应用的潜在挑战和机遇。
