Synthesis, Crystal Structure, and Magnetic Property of One 3D Nickel Coordination Polymer Based on 2-Hydroxy-5-(3',5'-terephthalic acid) Pyridine and 1,4-Bis(1-imdazoly)benzene
摘要:
One novel nickel coordination polymer, {[Ni(OTP)(bib)1.5(H2O)]·2H2O}n (1, H2OTP=2-hydroxy-5-(3',5'-terephthalic acid) pyridine, bib=1,4-bis(1-imdazoly)benzene), has been synthesized and characterized by elemental analysis (EA), IR, powder X-ray diffraction (PXRD), and thermogravimetric (TG) analyses. The crystal of 1 crystallizes in monoclinic, space group P21/n with a=12.2860(5), b=13.8246(6), c=19.0140(8) Å, β=104.3870(1)°, V=3128.2(2) Å3, Z=4, C32H28N7NiO8, Mr=697.32, Dc=1.481 g/cm3, F(000)=1444 and µ(MoKα)=0.684 mm-1. The final R=0.0704 and wR=0.1764 for 5485 observed reflections with I>2σ(I) and R=0.1087 and wR=0.2010 for all data. Topology analysis reveals that complex 1 is a 3D 2-fold interpenetrated {44·66}-nov net based on the 1D [Ni(OTP)]n chain and the 2D [Ni2(bib)3]n sql sheet. And the variable-temperature magnetic susceptibility measurements exhibit weak antiferromagnetic coupling interaction.
