Abstract

Cyclotriphosphazenes having p-tolylethynyl and chloro substituents N 3P3C≡C(p-Tol)n,Cl6-n (1a: n = 2, 1b: n = 4; p-Tol = p-tolyl) were synthesized by the reaction of hexachlorocyclotriphosphazene (NPC12)3 with 2 equiv of LiC≡C(p-Tol) in THF. 1a and 1b were characterized by spectroscopic methods and elemental analyses. The reactions of 1a and 1b with octacarbonyldicobalt Co2(CO)8 produced cobalt clusters containing tetrahedral C2Co2(CO)6(p-Tol) cluster units; namely, tetranuclear cluster N3P3 C2Co 2(CO)6(p-Tol)2Cl4 (2) and hexanuclear cluster N3P3C2Co 2(CO)6(p-Tol)3C≡C(p-Tol)Cl2 (3). Crystal structures of 1a and 2 were determined by X-ray crystallography.
