Synthesis and Crystal Structures of a Novel Nickel-Sodium Complex with Nitrilotriacetamides

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.
