Five isostructural tetranuclear lanthanide complexes with the general formula [Ln 4 (teaH 2 ) 2 (teaH) 2 (NO 3 ) 6 ] · 2CH 3 OH [Ln 3+ = Dy 3+ ( 1 ), Tb 3+ ( 2 ), Ho 3+ ( 3 ), Er 3+ ( 4 ), and Gd 3+ ( 5 )] were successfully synthesized by the reaction of various lanthanide nitrate and triethanolamine (teaH 3 ) ligand. Single crystal X‐ray analyses reveal the eight‐coordinate Ln 3+ centers adopt a slightly distorted triangular dodecahedron geometry and nine‐coordinate Ln 3+ ions own an approximately capped square antiprism environment in similar zigzag Ln4 core. Magnetic studies demonstrate the presence of anitferromagnetic interactions between Ln 3+ centers without obvious SMM behavior.
