| Abstract: | The new coordination polymer, {Cd2(L1)3(sac)4]?2CH2Cl2}∞:, has been prepared from the reaction of 1,4-bis(4-pyridyl)-2,3-diaza-1,3-butadiene (L1) with Cd(sac)2(H2O)4].2H2O(sac = saccharinate) in a methylene chloride/ethanol solvent mixture. The compound features a non-interpenetrating ladder motif constructed from Cd(L1)3 T-shaped units. The Cd atoms are coordinated to three nitrogen donor atoms from three L1 ligands and two nitrogen donor atoms from two saccharinate ligands in a rare, trigonal bipyramidal coordination environment. The compoundwas further characterized by IR spectroscopy and DTA/TGA. {Cd2(L1)3(sac)4]?2CH2Cl2}∞: crystallizes in the triclinic space group P-1 with a = 10.8747(19)Å, b = 12.626(2)Å, c = 15.749(3)Å, α = 111.839(3)°, β = 97.442(3)., and γ = 106.239(3)° |
