Cleavage reactions of the dinuclear [{Ni(′S2C ′)}2] · DMF (′S2C ′ 2–= 1,3‐imidazolidinyl‐N,N′‐bis(2‐benzenethiolate)(2–)) with HNPiPr3or HNSPh2yielded the mononuclear complexes [Ni(NHPiPr3)(′S2C ′)] (1) and [Ni(NHSPh2)(′S2C ′)] (2) which have been completely characterized. The nickel‐carbene‐dithiolate [Ni(′S2C ′)] moiety is one of the very rare complex fragments that are able to coordinate both HNPR3or HNSR2. IR spectra and X‐ray structure determinations show that 1and 2exhibit intramolecular N–H…S(thiolate) hydrogen bonds. Geometric parameters and NMR spectroscopic data of 1and 2are compatible with N–X single bonds and ylidic structures of the HNPiPr3and HNSPh2ligands. Comparison of Ni–N distances in diamagnetic and paramagnetic [Ni(NHSPh2)] complexes was rendered possible through the X‐ray structure determination of the homoleptic [Ni(NHSPh2)6]Cl2(3) which formed as minor by‐product in the synthesis of 2. |
