Abstract: The title compound, [Nd(dmso)7Cl][Bph4]2(dmso=dimethylsulfoxide, Bph4=tetraphenylboron anion) was synthesized in organic solvent acetone/EtOH and the structure was determined by single-crystal X-ray diffraction. The crystal is triclinic with space group P, and the crystal data are as follows: a=1.2554(1) nm, b=1.2799(1) nm, c=2.4598(3) nm; α=93.53(1)°, β=104.50(1)°, γ=112.77(1)°, V=3.4722(6) nm3, Z=2, Mr=1365.01, Dc=1.306 g·cm-3. The crystal is composed of a big cation [Nd(dmso)7Cl]2+ and two big anions [BPh4]-. The Nd3+ is coordinated by a chlorine atom and seven oxygen atoms from seven dimethylsulfoxides forming a distorted square antiprism coordination polyhedron,while the BPh-4 anion is charge-equilibrium ion.
