Crystal structure of silver [(propane-1,3-diyl-dinitrilo-?2N,N')-tetra-acetato-?4O,O',O'',O''']chromate(III) from synchrotron X-ray data.

ABSTRACT: The asymmetric unit of the title compound, Ag[Cr(C11H14N2O8)]·3H2O, contains one [Cr(1,3-pdta)]- anion [1,3-pdta is (propane-1,3-diyldi-nitrilo)-tetra-acetate], one Ag+ cation and three water mol-ecules. The Cr3+ ion is coordinated to the four O and two N atoms of the 1,3-pdta ligand, displaying a distorted octa-hedral geometry. The mean Cr-N and Cr-O bond lengths are 2.0727?(17) and 1.9608?(15)?Å, respectively. The conformations of the chelate rings were found to be envelope for the glycinates and twist-boat for the six-membered di-amine (T) ring. The Ag+ cation is surrounded by six O atoms from three non-coordinated carbonyl O atoms of neighbouring 1,3-pdta groups and three water mol-ecules. The crystal structure is stabilized by inter-molecular hydrogen bonding involving the water O-H group as donor and the carboxyl O atom as acceptor.
