A BINUCLEAR NICKEL(II) COMPLEX CONTAINING AN OXAMIDO-BRIDGE - SYNTHESIS, PROPERTIES AND X-RAY CRYSTAL-STRUCTURE OF [NI(OXAE)NI(PHEN)(2)](CLO4)(2)CENTER-DOT-3H2O
Pr. Wei et al., A BINUCLEAR NICKEL(II) COMPLEX CONTAINING AN OXAMIDO-BRIDGE - SYNTHESIS, PROPERTIES AND X-RAY CRYSTAL-STRUCTURE OF [NI(OXAE)NI(PHEN)(2)](CLO4)(2)CENTER-DOT-3H2O, Polyhedron, 14(3), 1995, pp. 441-444
The binuclear complex [Ni(oxae)Ni(phen)2](ClO4)(2) . H2O (oxae=N,N'bis
(2-aminoethyl) oxamido dianion, phen = 1, 10-phenanthroline) was prepa
red from the planar monomeric complex Ni(oxae) and characterized throu
gh analytical and spectroscopic measurements. The structure of [Ni(oxa
e)Ni(phen)(2)] (ClO4)2 . 3H(2)O was investigated by single-crystal X-r
ay analysis. The complex has an extended oxamido-bridged structure and
consists of two nickel(II) ions, one of them in a square planar envir
onment and another in a distorted octahedral environment. The Ni-Ni di
stance is 5.267 Angstrom.
