Coordination behavior of PPh ₂ {C ₆ H ₄ [CH ₂ N(CH ₂ CH ₂ ) ₂ O]-2}: Case study CdCl ₂ [PPh ₂ {C ₆ H ₄ [CH ₂ N(CH ₂ CH ₂ ) ₂ O]-2}]

Abstract

Abstract The reaction between CdCl 2 and PPh 2 {C 6 H 4 [CH 2 N(CH 2 CH 2 ) 2 O]-2} ( 1 ) in a 1:1 molar ratio resulted in the cadmium(II) complex CdCl 2 [PPh 2 {C 6 H 4 [CH 2 N(CH 2 CH 2 ) 2 O]-2}] ( 2 ). The complex 2 was characterized in solution by NMR spectroscopy ( 1 H, 13 C, and 31 P). Single-crystal X-ray diffraction studies revealed no intramolecular N→P interaction in 1 . The phosphane ligand behaves as a P,N chelating moiety in the cadmium complex 2 , thus resulting in a species containing distorted tetrahedral environments around cadmium and phosphorus. Short intermolecular interactions CH‧‧‧π aryl and CH‧‧‧O in 1 and CH‧‧‧π aryl and CH‧‧‧Cl in 2 resulted in supramolecular networks.
