Abstract
The reaction of 3-(3-pyridyl)acrylic acid (H(3-PYA)) with Co(NO3)2?6H2O or MnCl2?4H2O yielded two new complexes: [Co(3-PYA)2(H2O)4?H2O] 1 and [Mn(3-PYA)2(H2O)4] 2. Complex 1 crystallizes in monoclinic, space group C2/c with a = 9.9473(12), b = 13.7227(16), c = 14.7376(18) ?, β = 99.043(2)°, V = 1986.7(4) ?3, Z = 4, Dc = 1.549 g/cm3, μ = 0.921 mm-1, F(000) = 964, R = 0.0786 and wR = 0.1443. Six types of hydrogen bonds and π-π packing interactions connect the mononuclear units [Co(II)(3-PYA)2(H2O)4?H2O] into a three-dimensional supra- molecular architecture. Complex 2 crystallizes in monoclinic, space group P21/n with a = 11.3630(16), b = 7.0346(10), c = 12.1365(18) ?, β = 112.545(3)o, V = 896.0(2) ?3, Z = 2, Dc = 1.997 g/cm3, μ = 0.785 mm-1, F(000) = 438, R = 0.0787 and wR = 0.1550. The discrete entity Mn(II)(3-PYD)2(H2O)4 is extended into a 3-D supramolecular architecture by four kinds of hydro- gen bonds.
