To seek the effect that condition of complexes has on manufacture biaryl compounds, seven Ni(II) complexes, namely, {[Ni(L)0.5(bpa)(H2O)]·2H2O}n (1), {[Ni2(L)(dpp)2(H2O)]·4H2O}n (2), {[Ni(L)0.5(pbmb)(H2O)]·H2O}n (3), {[Ni2(L)(bmp)2(H2O)]·7H2O}n (4), {[Ni(L)0.5(pbib)1.5]·2H2O}n (5), {[Ni2(L)(pbib)1.5]·3H2O}n (6), and [Ni(L)0.5(beb)2(H2O)]n (7) (bpa = 1,2-bis(4-pyridyl)ethane, dpp 1,3-di(4-pyridyl)propane, pbmb 1,1′-(1,3-propane)bis(2-methylbenzimidazole), bmp 1,5-bis(2-methylbenzimidazol) pentane, pbib 1,4-bis(imidazol-1-ylmethyl)benzene, beb 1,4-bis(2-ethylbenzimidazol-1-ylmethyl)benzene), have been gained through hydro(solvo)thermal reactions 5,5′-(hexane-1,6-diyl)-bis(oxy)diisophthalic acid ligand (H4L) with metal ions under regulation control six N-donor ligands. 3-fold interpenetrating complex 1 belongs to a (4,4)-connected 3D bbf net vertex symbol (64·82)(66) topology. 2 presents (4,4,4)-connected Schläfli (66)2(64·82) 3 features (3,4)-connected 3,4L13 topology (4·62)(42·62·82) 4 possesses mog Moganite network fabric, is (4·64·8)2(42·62·82). 5 takes (4,5)-connected architecture, point (4·69)(42·66·82). 6 (4,7)-connected framework, (45·5)(47·53·611). 7 4,4L28 topology, (Schläfli) (42·64)(4·64·8). A systematic structural comparison 1–7 signifies their frameworks can be regulated varied conformations flexible H4L diverse Between proximal ions, variable-temperature (2–300 K) magnetic susceptibilities display overall weak antiferromagnetic coupling. In complexes-catalyzed homocoupling reaction iodobenzene, 3, 5, 6, verified effectual catalysts for synthesis compounds.
