Synthesis and characterization of some transition metal complexes of trimeric and tetrameric aminocyclophosphazenes

Reactions of aminocyclotri-and aminocyclotetra-phosphazenes,viz., N3P3L6 an d N4P4L8 (L = -HN(sec - C4H9), -NHC6H11, - HNC8H17, -NC5H10 and -NC4H8O) wi th hydrated Cu(II), Co(II), Ni(II) and Fe(III) chlorides have been studied. CuCl2. 2H(2)O give only [(N3P3L6H or N4P4L8H)CuCl3] whereas with CoCl2. 6H (2)O, a mixture of two products, namely, [(N3P3L6H or N4P4L8H)CoCl3] and [( N3P3L6H or N4P4L8H)](2)[CoCl4] are recovered. FeCl3. 6H(2)O and NiCl2. 6H(2 )O give only ionic products of the type [(N3P3L6H)][FeCl4] and [(N3P3L6H)]( 2)[NiCl4]. A few reactions of N3P3L6 (L = -HN(sec-C4H9), -HNC6H13 and -HNC8 H17) with Mo(CO)(6) have also been carried out. In these reactions [(N3P3L6 )Mo(CO)(3)] derivatives are obtained. The complexes have been characterized by analytical data, conductivity, magnetic and IR measurements.
