A new coordination polymer, [Zn2(m-bix)(p-bdc)2](1), was synthesized under hydrothermal conditions by a reaction of 1,3-bis(imidazol-1-ylmethyl)benzene(m-bix), 1,3-benzenedicarboxylic acid(H2p-bdc) and Zn(NO3)2. The colorless block crystals of complex 1(C30H22N4O8Zn2) belong to the triclinic system, space group P1 with a = 10.213(2), b = 12.052(2), c= 12.392(3) A, α = 82.97(3), β = 76.04(3), γ = 78.02(3)o, V = 1443.8(5) A3, Z = 2, Dc = 1.604 g/cm-3,Mr = 697.26, F(000) = 708, R = 0.0403 and w R = 0.0907 for 4886 observed reflections(I > 2σ(I)). In1, the tetrahedral ZnI I cations are linked by [p-bdc]2– anions into 2D sq1 networks, which are further connected by bix ligands forming an interesting 2-fold 4,4-connected mog-type 3D network with a point symbol of {4·64·8}2{42·62·82}. Complex 1 was characterized by elemental, IR spectroscopy,powder X-ray diffractions and thermalgravimetric analysis. In addition, complex 1 exhibits coordination induced photoluminescent property.
A new coordination polymer, [Zn2 (m-bix) (p-bdc) 2] (1) was synthesized under hydrothermal conditions by a reaction of 1,3-bis 1, 3-benzenedicarboxylic acid (H2p-bdc) and Zn (NO3) 2. The colorless block crystals of complex 1 (C30H22N4O8Zn2) belong to the triclinic system, space group P1 with a = 10.213 (2), b = 12.052 Α = 82.97 (3), β = 76.04 (3), γ = 78.02 (3) o, V = 1443.8 (5) A3, Z = 2, Dc = 1.604 g / cm3, Mr = 697.26, F (000) = 708, R = 0.0403 and wR = 0.0907 for 4886 observed reflections (I> 2σ (I)). In1, the tetrahedral ZnI I cations are linked by [p-bdc ] 2-anions into 2D sq1 networks, which are further connected by bix ligands forming an interesting 2-fold 4,4-connected mog-type 3D network with a point symbol of {4.64.8} 2 {42.62 · 82}. Complex 1 was characterized by elemental, IR spectroscopy, powder X-ray diffractions and thermal gravimetric analysis. In addition, complex 1 exhibits coordination induced photoluminescent property.
