A one dimensional coordination polymer: poly{[[(u-dcpdaa-K4-O1:O2:O3:O4)(MeOH)2 Copper(II)]bis[(aquo)(dcpdaa-K4-O1:O2:O3:N1)Copper(II)]] dihydrate}
Abstract
The new title one-dimensional homo-trinuclear Cu3 coordination polymer {[Cu3(HL2)2(H2O)2(CH3OH)1.18)]. 2H2 O}n (1) was isolated as a green solid by heating a mixture of 2,5-(bis(dicarboxyphenyl)diacetic acid amine (dcpdaa) with Cu (NO3)2 in methanol in the presence of NaOH. The coordination polymer has been characterized by FTIR and X-ray single crystal diffraction. It consists of two dependent Copper (II) centers were linked by a six-coordinate Cu (II) ion through the carboxylic oxygen ligands o HL3-. The two dependent Cu (II) centers, features two very similar pyramidal with CuNO4 chromophores. Three-dimensional metal-organic framework were constructed via H-bonding of the terminal non-bonded carboxylic group of the ligand with lattice water molecules.
