Three new lanthanide complexes with the formulae [Eu 2 (TsGly) 6 (phen) 2 (H 2 O) 2 ] ( 1 ), [Ln(TsGly) 2 (phen) 2 (H 2 O) 2 ]Cl · 2H 2 O [Ln=Er ( 2a ) and Yb ( 2b ), TsGly N ‐ p ‐tolylsulfonylglycinate, phen1,10‐phenanthroline] were synthesized. Crystallographic data for 1 : monoclinic, P 2 1 / n , a =1.29791(16) nm, b &=1.9034(2) nm, c =1.7596(2) nm, β =93.410(3) °, V =4.3394(9) nm 3 , Z =4, R 1 =0.0326, wR 2 =0.0771; and for 2b : triclinic, P 1, a =1.2674(2) nm, b =1.4405(2) nm, c =1.4809(3) nm, α =113.256(3) °, β =108.253(3) °, γ =94.739(3) °, V =2.2922(7) nm 3 , Z2, R 1 =0.0292, w R 2 =0.0669. X‐ray diffractional analysis reveals that compound 1 adopts dinuclear structure with fourfold bridging TsGly ligands between the Eu(III) centers, while compound 2b features an unusual mononuclear structure.
