Synthesis and structural characterization of a Ni(II) coordination polymer with a tripodal 4-imidazolyl-functional ligand

1,3,5-Tri(1H-imidazol-4-yl)benzene (H3L) reacts with Ni(ClO4)2 · 6H2O under hydrothermal conditions at T = 100°C to yield a new complex: [Ni(H2L)2] · 5.5H2O (1). The product is characterized by single crystal and powder X-ray diffraction, infrared spectroscopy, and elemental and thermogravimetric analyses. Complex 1 crystallizes in the monoclinic space group C2/c and exhibits a binodal (3,6)-connected 2D kgd network structure with (43)2(46.66.83) topology.
