To explore the chemical analogy between thorium and heavier actinides in soft anionic environments, three new thorium phosphides (ThCuP 2 , β-ThCu 2 P 2 , and ThCu 5 P 3 ) have been prepared through solid-state reactions using CuI as a reaction promoter. The structure of ThCuP 2 can be described as a filled UTe 2 -type with both dimeric P 2  4- and monomeric P 3- anions, in which Th is coordinated by eight P atoms in a bicapped trigonal prismatic arrangement and Cu is tetrahedrally coordinated by four P atoms. β-ThCu 2 P 2 contains only P 3- anions and is isostructural with BaCu 2 S 2 . In this structure, Th is coordinated by seven P atoms in monocapped trigonal prismatic geometry and Cu is tetrahedrally coordinated by four P atoms. ThCu 5 P 3 adopts the YCo 5 P 3 -type structure consisting of P 3- anions. This structure contains Th atoms coordinated by six P atoms in a trigonal prismatic arrangement and Cu atoms that are either tetrahedrally coordinated by four P atoms or square pyramidally coordinated by five P atoms. Electric resistivity measurements and electronic structure calculations on β-ThCu 2 P 2 indicate a metal. These new compounds may be charge-balanced and formulated as Th 4+ Cu + (P 2  4- ) 1/2 P 3- , Th 4+ (Cu + ) 2 (P 3- ) 2 , and Th 4+ (Cu + ) 5 (P 3- ) 3 , respectively. The structural, bonding, and property relationships between these Th compounds and related actinide and rare-earth phases are discussed. Titled compounds display more diverse ion-ion interactions and different electronic structures from those in UCuP 2 and UCu 2 P 2 hat were synthesized under similar experimental conditions, suggesting divergence of thorium-phosphide chemistry from uranium-phosphide chemistry.
