The title complex 1·THF has been synthesized by the reaction of [HO-4,6-di-tBu- C6H2-2-CH2{CH(iPrNCHCHN)}]Cl with NdCl3 in a 2:1 molar ratio in THF, and characterized by single-crystal X-ray diffraction. It crystallizes in monoclinic, space group P21/c with a = 9.6501(14), b = 16.393(2), c = 36.745(6) , β = 97.444(4)o, V = 5763.7(15) 3, Mr = 1124.69, Z = 4, Dc = 1.296 g/cm3, μ(MoKα) = 1.175 mm-1, F(000) = 2348, the final R = 0.0729 and wR = 0.1762 for 8735 observed reflections with I > 2σ(I). Complex 1 consists of an anion [NdCl5(THF)]2- and two cations [HO-4,6-di-tBu-C6H2-2-CH2{CH(iPrNCHCHN)}]2+ to form a layer structure by the interconnection of anions and cations via hydrogen bonding. The central metal Nd in the anionic unit is coordinated by five Cl atoms and one oxygen atom from solvated THF molecule assuming a distorted octahedral geometry. The title complex 1 · THF has been synthesized by the reaction of [HO-4,6-di-tBu- C6H2-2-CH2 {CH (iPrNCHCHN)}] Cl with NdCl3 in a 2: 1 molar ratio in THF, and It crystallizes in monoclinic space group P21 / c with a = 9.6501 (14), b = 16.393 (2), c = 36.745 (6) , β = 97.444 (4) o , V = 5763.7 (15) 3, Mr = 1124.69, Z = 4, Dc = 1.296 g / cm3, μ (MoKα) = 1.175 mm -1, F (000) = 2348, final R = 0.0729 and wR = Complexes consist of an anion [NdCl5 (THF)] 2- and two cations [HO-4,6-di-tBu-C6H2-2-CH2 {CH (iPrNCHCHN )}] 2+ 2+ to form a layer structure by the interconnection of anions and cations via hydrogen bonding.
