Hydrothermal Syntheses, Crystal Structures and Characteristics of Two New Isostructural Ni(II) Coordination Polymers
摘要:
Two new isostructure nickel(Ⅱ) coordination polymers,[Ni2(5-Me-ip)(1,2-Bie)(H2O)2]n (1) and [Ni2(5-Br-ip)(1,2-Bie)(H2O)2]n (2) (5-Me-H2ip=5-methylisophthalic acid, 5-Br-H2ip=5-mromoisophthalic acid, 1,2-Bie=1,2-bis(imidazole)ethane), have been synthesized and structurally characterized by single-crystal X-ray diffraction. The result shows that complexes 1 and 2 crystallize in orthorhombic system, space group Pna21 with a=16.3602(13), b=10.1465(8), c=21.8803(17) Å, V=3632.1(5) Å3, Z=4, Dc=1.525 g/cm3, F(000)=1728, R=0.0292 and wR=0.0668 for 6646 observed reflections (I>2σ(I)) for complex 1 and a=16.409(3), b=10.1625(17), c=21.918(4) Å, V=3654.9(11) Å3, Z=4, Dc=1.752 g/cm3, F(000)=1936, R=0.0309 and wR=0.0600 for 6809 observed reflections (I>2σ(I)) for complex 2. They both feature zigzag 2D layer structures, which are further staked along the a-axis through π…π and hydrogen interactions to form 3D supramolecular structures.
