The reactions of Re2(CO)9(NCMe) and Re3(CO)10(CH3CN)2(μ-H) 3 with S=C(NEt2)N(H)(p-tolyl) have yielded the new compounds Re2(CO)9[S=C(NEt2)N(H)(p-tolyl)] (1) and Re3(CO)10[μ-SC(NEt 2)N(H)(p-tolyl)](μ-H)3 (2) in 89% and 98% yields, respectively. Compounds 1 and 2 were characterized by single-crystal X-ray diffraction analyses. Compound 1 contains an S-coordinated S = C(NEt2)N(H)(ptolyl) ligand terminally coordinated in an equatorial coordination site on one of the rhenium atoms. Compound 2 con-tains the first example of an S-coordinated bridging thiourea grouping. When solutions of i were heated to 97°C, it was transformed to the new compound {Re(CO)3[μ-SC(N-ptolyl)(NEt2)]}2 (3) plus Re2(CO)10. Compound 3 is a centrosymmetrical dimer of the unit Re(CO)3[SC(N-p-tolyl)(NEt2)] in which the sulfur atom bridges the two rhenium atoms. The tolyl-substituted nitrogen atoms are coordinated to the rhenium atoms to form two Re-S-C-N rings. VCH Verlagsgesellschaft mbH 1996.
