The starting Eu(C10H12NS2)3(1,10-phenanthroline)] complex was prepared following the method described by Su et al. (1995). Recrystallization of this complex from chloroform solution yielded crystals of (I) (m.p. 416–418 K).
All H atoms were fixed geometrically in ideal positions and allowed to ride on their parent C atoms, with C—H = 0.93 Å (aromatic), 0.99 Å (methine) and 0.97 Å (methyl), and with Uiso(H) = 1.2Ueq(aromatic and methine-C) and 1.5Ueq(methyl-C). Atom C13 was found to be disordered and was refined isotropically in two alternative positions, with refined occupancy factors of 0.71 (2) and 0.29 (2).

Some metal–dithiocarbamate complexes are not stable in solution and, upon recrystallization, lead to the formation of decomposition products. One such example is dipyrrolidinylthiuram disulfide, which was obtained from the recrystallization of [Fe{S2CN(CH2)4}3] from methanol solution (Yamin et al., 1996). Similarly, the title compound, (I), was obtained after recrystallization from a chloroform solution of [Eu(S2NC10H13)3(1,10-phenanthroline)].
The molecular structure of (I), Fig. 1, is isostructural with other thiuram disulfides, such as tetraethylthiuram disulfide (Karle et al., 1967) and bis(N-methyl,N-phenyl-thiocarbamoyl)disulfide (Fun et al., 2001). The S—S, C10—S2, C10—S1, C11—S3 and C11—S4 bond distances in (I) are in agreement with these thiuram disulfides (Table 1). However, the C10—S2—S3—C11 torsion angle of 78.70 (13)° is smaller than the value of approximately 96° observed in tetraethylthiuram disulfide (Karle et al., 1967).
Each of the S3/S4/N2/C11/C15 and S1/S2/N1/C7/C10 fragments is planar, with the maximum deviation for either of these being 0.027 (2) Å for atom N1. The dihedral angle between the two least-squares planes through these groups is 80.10 (7)°. The two phenyl groups, C1–C6 and C15–C20, are inclined to each other by 67.70 (15)°.
The molecule of (I) is stablized by intramolecular interactions, with C7—H7···S1 2.59 Å [C7···S1 is 3.068 (4) Å], and the angle subtended at the H atom is 110°.
