Tris(1,10-phenanthroline-κ2N,N′)cobalt(II) bis-(2,4,5-tri-carb-oxy-benzoate) monohydrate

摘要

In the complex cation of the title salt, [Co(C 12 H 8 N 2 ) 3 ](C 10 H 5 O 8 ) 2 ·H 2 O, the Co II cation is situated on a twofold rotation axis and is coordinated in a distorted octa-hedral manner by six N atoms from three chelating 1,10-phenanthroline (phen) ligands. In the crystal, the non-coordinating 2,4,5-tri-carb-oxy-benzoate anions inter-act with each other via O—H?O hydrogen bonds, generating a two-dimensional network parallel to (100). Adjacent sheets are connected by water O—H?O carboxyl-ate hydrogen bonds, resulting in a three-dimensional network structure that surrounds the complex cations.
