A novel two-dimensional compound [Ni0.5(H2O)1.5{Ni(en)2}3V18O42(Cl)]·3.5H2O 1 has been hydrothermally synthesized and characterized by IR, elemental analysis, and single-crystal X-ray diffraction analysis. Crystal data for 1: monoclinic, space group C2/c with a=12.824(3), b =27.873(6), c=21.092(4) A, β=92.93(3)°, V=7529(3) A3, Z=4, Dc= 2.012 g/cm3, Mr= 2280.56,F(000)=4476 andμ=3.092 mm -1. The final R and wR are 0.0769 and 0.1783, respectively for 4203 observed reflections with I＞2σ(I). The structure consists of [V18O42(Cl)]7- clusters linked by trans- {Ni(en)2} groups into linear chains, while cis-{Ni(en)2} groups provide the cross-linking adjacent chains to form a two-dimensional structure.
