Abstract

A novel complex with nitrilotriacetamides (abbreviation L) has been synthesized. Single-crystal X-ray diffraction analysis determined the molecular formula as C₁₂H₂₈N₈Na₂NiO₁₀. 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. 

Keywords: Crystal structure, nitrilotriacetamide, nickel complex.
