Three new ternary copper phosphides, Sr 2Cu 6P 5, Eu 2Cu 6P 5, and EuCu 4P 3, have been synthesized from the elements in evacuated silica capsules. Eu 2Cu 6P 5 and Sr 2Cu 6P 5 adopt the Ca 2Cu 6P 5-type structure, while EuCu 4P 3 is isostructural to BaMg 4Si 3 and still remains the only representative of this structure type among the ternary Cu pnictides. All three materials show metallic conductivity in the temperature range 2 K T 290 K, with no indication for superconductivity. For Eu 2Cu 6P 5 and EuCu 4P 3, long-range magnetic order was observed, governed by 4f local moments on the Eu atoms with predominant ferromagnetic interactions. While Eu 2Cu 6P 5 shows a single ferromagnetic transition at T C = 34 K, the magnetic behavior of EuCu 4P 3 is more complex, giving rise to three consecutive magnetic phase transitions at 70, 43, and 18 K.
