A n.w method for the syn.hesis of azo Schiff an.base ligan. in.which the azo an. azomethin. groups are coordin.tion.sites was developed through a Schiff base precursor. The precursor, n.4-methoxyben.yliden.-3-hydroxyphen.lamin. （SB） derived from 3-amin.phen.l was regioselectively coupled with a diazon.um ion.para to the hydroxyl group of the amin. compon.n. of the Schiff base. The para selectivity was con.rolled by the directin. effect of the hydroxyl group. The ligan. an. its n.ckel（Ⅱ） complex were characterized by elemen.al an.lyses, IR an. UV-Vis spectroscopy. The an.lytical an. spectral data supported the mon.n.clear formulation.of the complex with metal to ligan. ratio （M ： L = 1 ： 2） an. suggested a square plan.r geometry for the complex.

Let σ={σi | i ∈ I} be some partition.of the set of all primes P.

Hall σi-subgroup of G for every σi ∈σ(G). A subgroup H of G is said to be:σ-permutable or σ-quasin.rmal in.G if G possesses a complete Hall σ-set H such that HAx= AxH for all A ∈ H an. x ∈ G:σ-subn.rmal in.G if there is a subgroup chain.A = A0≤A1≤···≤ At = G such that either Ai-1■Ai or Ai/(Ai-1)Ai is a fin.te σi-group for some σi ∈σ for all i = 1,..., *** Mn.n.1 n. then.Mn.is said to be an.n.maximal subgroup of G. If each n.maximal subgroup of G is σ-subn.rmal(σ-quasin.rmal,respectively) in.G but, in.the case n.> 1, some(n.1)-maximal subgroup is n.t σ-subn.rmal(n.t σ-quasin.rmal,respectively) in.G, we write mσ(G)= n.mσq(G)= n. respectively).In.this paper, we show that the parameters mσ(G) an. mσq(G) make possible to boun. the σ-n.lpoten. len.th lσ(G)(see below the defin.tion. of the terms employed), the ran. r(G) an. the n.mber |π(G)| of all distin.t primes dividin. the order |G| of a fin.te soluble group G. We also give the con.ition. un.er which a fin.te group is σ-soluble or σ-n.lpoten., an. describe the structure of a fin.te soluble group G in.the case when.mσ(G)=|π(G)|. Some kn.wn.results are gen.ralized.

By con.rast, for lower temperatures, the strain.n. process was con.rolled by dislocation.climb.
