Coordination d'anions organophosphorés. IV. Préparation et identification cristallographique de différentes phases de nitratocomplexes du cobalt(II), du nickel(II) et du zinc(II)

Abstract

Chemical preparations and crystal data are described for the new nitratocomplexes {M(NO3)L} where M 2. is a metallic ion Co 2 +, Ni 2 +, Zn 2 + and L-the anion {(CzH50)2P(O)CHCOCHzR} -with R an amino group. The isolation of one or many crystalline forms depends on the nature of the radical R. These different species have been characterized by their space groups and the powder patterns of the monoclinic forms have been indexed from the single-crystal dimensions.Nous avons analys6 la r6activit6 des v-amino fl-c6tophos-phonates (C2HsO)EP(O)CHECOCH2 R d6sign6s par LH (LaH, R=N(CH3)2;LbH, R=N(CEHs)2; LcH, R= lklCH2CH2OCH2(2H2 ; LdH, R = lqCH2CH2CH2CH2CH2) en pr6sence de nitrates m6talliques {M(OH2)6} (NO3)2,
