Abstract: | Four new organic/inorganic coordination polymers, Cd(C(10)H(8)N(2))(2)(H(2)O)(2)(NO(3))(2)](n)(1), Co(C(10)H(8)N(2))(H(2)O)NO(3)CH(3)OH](n)(2), Cu(C(10)H(8)N(2))(CH(3)OH)(NO(3))(2)](n) (3), and Cu(C(10)H(8)N(2))(hfac)(2)](n)(4), were synthesized by using the rigid ligand 1,2-bis(3-pyridyl)ethyne (3,3'-DPA). Complex 1 crystallizes in space group P2/n: a = 12.462(2) A, b = 9.485(1) A, c = 13.383(2) A, beta = 96.629(2) degrees, V = 1559.6(3) A(3), Z = 4. Complex 2 crystallizes in space group Fddd: a = 9.248(4) A, b = 19.982(7) A, c = 35.093(16) A, V = 6485.0(4) A(3), Z = 8. Complex 3 crystallizes in space group I2/a: a = 18.315(2) A, b = 8.517(1) A, c = 20.494(3) A, beta = 104.042(2) degrees, V = 3101.2(7) A(3), Z = 8. Complex 4 crystallizes in space group P21/c: a = 6.576(1) A, b = 16.189(1) A, c = 11.653(1) A, beta = 91.337(1) degrees, V = 1240.3(2) A(3), Z = 2. The coordination polymers display a variety of structural architectures, ranging from sinusoidal and zigzag chains (1, 3, 4) to two-dimensional channel-type architectures (2). The effects of the orientation of the nitrogen atom in the pyridine rings on the resultant structures are discussed. |
