Single crystals of [ Ni2L2phen] suitable for X-ray diffraction studies were grown from its solution in a mixture of dimethylformamide and methanol (1:1) by slow evaporation at room temperature in ari.A single crystal of dimensions 0.33*0.16*0.11 MM3 with p1 symmetry was selected and mounted on a CeysAlis CCD diffractomeeter, equipped with an ewnhhance (Mo) X-ray source. The compound was diffracted by CeysAlis CCD, Oxford Diffraction Ltd. With graphite-monochromated Mo Kα (λ=0.71073 Å) radiation. The trial structure was solved by direct methods with the program SHELXS-97 and refined by full matrix least-squares on F2 using SHELXS-97[14]. The crystal data and structure refinememt parameters for [ Ni2L2phen] are given in Table 1
