A heteronuclear [nickel(II)–sodium] infinite chain complex derived from 3-{[(2-diethylamino-ethyl)-methyl-amino]-methyl}-2-hydroxy-5-methyl-benzaldehyde

The asymmetric compartmental proligand HL bearing a tridentate N2O donor set and a bidentate OO donor set has given the novel heteronuclear [Ni(II)–Na] infinite chain polymer in which the molecular structure has a repeating Na/Ni5 unit of formula [Ni5Na(L)2(OAc)6(OH)2(BPh4)]n.
