CdGeP2 is Lavarevi\'{c}ite-like structured and crystallizes in the trigonal R3m space group. Cd(1) is bonded to one P(1) and three equivalent P(2) atoms to form CdP4 tetrahedra that share corners with six equivalent Cd(1)P4 tetrahedra and corners with six equivalent Ge(1)P4 tetrahedra. Ge(1) is bonded to one P(2) and three equivalent P(1) atoms to form GeP4 tetrahedra that share corners with six equivalent Cd(1)P4 tetrahedra and corners with six equivalent Ge(1)P4 tetrahedra. There are two inequivalent P sites. In the first P site, P(1) is bonded to one Cd(1) and three equivalent Ge(1) atoms to form PCdGe3 tetrahedra that share corners with six equivalent P(2)Cd3Ge tetrahedra and corners with six equivalent P(1)CdGe3 tetrahedra. In the second P site, P(2) is bonded to three equivalent Cd(1) and one Ge(1) atom to form PCd3Ge tetrahedra that share corners with six equivalent P(2)Cd3Ge tetrahedra and corners with six equivalent P(1)CdGe3 tetrahedra.
