Sažetak

A series of cobalt(II), nickel(II) and copper(II) chloride complexes
with the tripode organophosphorous compounds: bis[(diphenylphosphinyl)
methyl]phenylphosphine oxide (RPPh) and bis
[(diphenylphosphinyl)methyl]phosphinic acid (RPOH) were studied.
Complexes of the general stoichiometry [M(RPPh)s] [MC14] • 4H20
and fM(RPOH)Cl · nH20]m (M = Co(II), Ni(II) or Cu(II); n = 0 - 4,
m = 1, 2 or more) were isolated.
According to spectral and magnetic data, complexes with the
RPPh ligand appear to have both an octahedral and a tetrahedral
surrounding of the metal(II) ion.
For the complexes [M(RPOH)Cl · nH20]m the electronic effect
of the metal ion seems to be predominant. A tetrahedra<! surrounding
for the cobalt(II) complex, an octahedral surrounding for
the nickel(II) complex and a tetragonal distorted octahedral surrounding
for the copper(II) complex has to be assumed.
