Abstract: | In the title compound, [Cu(C12H15N4S2)(C18H15P)], the copper(I) center is tetrahedrally coordinated by one S atom and two N atoms from one bis(3,5‐dimethylpyrazol‐1‐yl)dithioacetate ligand and one P atom from a triphenylphosphine ligand. In the crystal structure, adjacent pyrazole rings are involved in weak π–π interactions, thereby forming a one‐dimensional zigzag chain running along the b axis. |
