A series of cationic complexes [Ln(Pip)2(Ph3PO)3]B(Ph)4·2H2O (Ln(III) = La, Nd, Еu, Lu;  HPip (CAPh type ligand) = 2,2,2-trichloro-N-(dipiperidin-1-yl-phosphoryl)acetamide) has been synthesized. The complexes have been characterized by means of the X-ray diffraction,  FT-IR spectroscopy and elemental analyse. Crystal structure of [Lа(Pip)2(Ph3PO)3] B(Ph)4·2H2O has been determined. Cell edge parameters: a = 15.3820 Å, b = 15.2050 Å, c =44.8980 Å, β = 92.98°, V = 10486.7Å3, space group P 21/c. Two CAPh ligands are coordinated via oxygen atoms of phosphoryl and carbonyl groups, forming six-membered cycles Schemes of [Lа(Pip)2(Ph3PO)3]BPh4·2H2O dissociation in nonaqueous solvents: acetone and methanol has been investigated. To determine the type of electrolyte value of electric conductivity at infinite dilution (λ0) was calculated.
