Popis:	The water-soluble chelating phosphine ligand tris(2-carboxyethyl)phosphine (TCEP) reacts with cobalt(II) chloride in water to give the mixed-valence Co(III)/Co(II)/Co(III) complex [Co{P(CH2CH2COO)2(CH2CH2COOH)}2]2[Co(H2O)4][Na2(H2O)4]Cl2 · 6H2O (1). Structural analysis of 1 using single-crystal X-ray diffraction reveals a trimetallic sodium bridged structure in which TCEP adopts a tridentate chelating mode towards Co(III), and a bridging mode towards Co(II) and Na ions.
