Synthesis and Crystal Structures of a mixed-metal Complex with Nitrilotriacetamides

Abstract

Abstract. A novel complex with nitrilotriacetamides(L) has been synthesized. Single-crystal X-ray diffraction analysis determined the molecular formula as C 12 H 28 N 8 Na 2 NiO 10 . The crystal belongs to the triclinic system with P-1 space group. In this molecule, the L ion exhibits an infrequent coordination mode. The nickel center is hexa-coordinated to a slightly distorted octahedral configuration by six nitrogen atoms from two L ligands. The sodium ion is six-coordinated with three oxygen atoms of ligands and three oxygen atoms of water molecules. Two water molecules bridge two Na + ions.
