[[mu]-6,9-Bis(carboxylatomethyl)-3,12-bis(carboxymethyl)-3,6,9,12-tetraazatetradecanedioato]bis[aquacobalt(II)] tetrahydrate

Q. Qian, J. Wu and J. Qian

Abstract: The binuclear title complex, [Co2(C18H26N4O12)(H2O)2]·4H2O, lies about a centre of inversion, the CoII atom being coordinated in a distorted octahedral arrangement defined by one water molecule and N2O3 donors derived from one end of a 6,9-bis(carboxylatomethyl)-3,12-bis(carboxymethyl)-3,6,9,12-tetraazatetradecanedioate (H2TTHA4-) tetraanion. In the crystal, numerous O-H...O hydrogen bonds link the molecules into a three-dimensional network.
