| Abstract: A new metal-organic coordination polymer [Mn(NIPH)(phen)2]·4H2O (1, H2NIPH=5-nitroisophthalic acid, phen=1,10-phenanthroline) has been hydrothermally synthesized and structurally characterized by elemental analyses, TG, IR spectroscopy and single-crystal X-ray diffraction. The complex crystallizes in monoclinic, space group P21/n with a=1.082 2(2) nm, b=2.288 3(5) nm, c=1.289 6(3) nm, β=105.11(3)°, V=3.083 2(11) nm3, C32H27MnN5O10, Mr=696.53, Dc=1.501 g·cm-3, μ(Mo Kα)=0.497 mm-1, F(000)=1 436, Z=4, the final R=0.059 2 and wR=0.134 5 for 4 079 observed reflections (I>2σ(I)). In the crystal structure, the manganese atom is six-coordinated with two carboxylate oxygen atoms from two different NIPH ligands and four nitrogen atoms from two phen ligands, showing a distorted octahedral geometry. Furthermore, it exhibits a 3D supramolecular network through hydrogen bonding and π-π stacking interactions. CCDC: 818823. |
