Syntheses, Crystal Structures, and Properties of Two Mixed-ligand Coordination Polymers: [Zn(bdc)(1,3-bimb)](n) and {[Mn-2(0x)(2)(1,3,5-tib)4/3 center dot 4H(2)O}(n)

Two new coordination polymers, [Zn(bdc)(1,3-bimb)](n) (1) and I[Mn-2(ox)(2)(1,3,5-tib)(4/3)].4H(2)O}(n) (2) (H(2)ox = oxalic acid, H(2)bdc = terephthalic acid, 1,3-bimb = 1,3-bis(imidazol-1-ylmethyl)benzene, 1,3,5-tib = 1,3,5-tri(imidazol-1-yl)benzene), were synthesized and characterized by elemental analysis, IR, powder X-ray diffraction (PXRD), and thermogravimetric (TG) analyses. X-ray diffracation analysis reveals that two kinds of zigzag chains [Zn(bdc)](n) and [Zn(1,3-bimb)](n) in compound 1 are interweaved to form a 3D 4-fold interpenetrated 6(6)-dia framework. In compound 2, Mn(1) and Mn(2) are linked via 1,3,5-tib ligands to form two different nets of [Mn-6(1,3,5-tib)(6)](n) along the ab plane with inner- or outer-shape N-Mn-N angles, which are connected by 1D infinite [Mn-2(ox)(2)](n) chains via Mn-O bonds to result in. a (3,3,3,4,4)-connected (4.8.10)(3)(4.8(2))3(4.8(3).10(2))6(8(2).10(4).3)(3)(8(3))(4) topology. Moreover, the photoluminescence of 1 has been investigated. The crystal of 1 crystallizes in orthorhombic, space group Pna2 with a = 13.2267(6), b = 9.1717(4), c = 17.4492(8) angstrom, V= 2116.79(16) angstrom(3), Z = 4, C22H18N4O4Zn, M-r= 467.77, D-c = 1.468 g/cm(3), F(000) = 960 and mu(MoK alpha) = 1.197 mm(-1). The final R = 0.0280 and wR = 0.0618 for 3695 observed reflections with I > 2 sigma(I) and R = 0.0389 and wR = 0.0653 for all data. The crystal of 2 crystallizes in rhombohedral, space group R-3 with a = 22.080(8), c = 31.19(2) angstrom, V = 13167(11) angstrom(3), Z = 18, C(24)H(25)Mu(2)N(8)O(13), M-r = 743.40, D-c = 1.688 g/cm(3), F(000) = 6822 and mu(MoK alpha) = 0.945 mm(-1). The final R = 0.0429 and wR = 0.1035 for 5160 observed reflections with I > 2 sigma(I) and R = 0.0824 and wR = 0.1244 for all data.
