CrCp*Tp was synthesized from the reaction of [CrCp*Cl]2 and KTp. Magnetic measurements indicate it to have a high-spin (S = 2) electronic configuration from 5 to 300 K. A single-crystal x-ray study reveals bond lengths typical for a high-spin configuration and a pronounced Jahn-Teller distortion. The nature of this distortion was probed by DFT calculations and the variation in bond lengths successfully reproduced. The metal-based HOMO is significantly antibonding with respect to a single pyrazolyl ring only.

Dimethylgold(III) and methylmercury(II) form complexes Me2AuL and MeHgL [L = poly(pyrazol-1-yl)borate ligands, e.g., [HB(pz)3]- and [B(pz)4]-]. The structure of Me2Au[HB(pz)3] was determined by single-crystal x-ray diffraction. This complex has square-planar coordination for the Au atom involving 2 coordinated pyrazole rings and 1 uncoordinated ring, in contrast to the isoelectronic cation [Me2Au[(pz)3CH]]+, which has square-planar coordination with a weak axial Au-N interaction. Variable-temperature 1H NMR in CD2Cl2 indicates a rapid equilibrium between pyrazole-ring environments at ambient temperature and, for the MeHgII complexes, down to -90°. For the Me2AuIII complexes, spectra at -90° indicate pyrazole-ring environments in ratios 2:1 [L = [HB(pz)3]-] and 2:1:1 [L = [B(pz)4]-].

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Journal of Organometallic Chemistry called Synthesis of a tris(pyrazolyl)borate-stabilized molybdenum alkylidene and its hydrolysis products. Crystal structures of TpMo(CH2C(Me)2Ph)(NAr)(O) and [TpMo(NAr)(O)]2O, Author is Vaughan, William M.; Abboud, Khalil A.; Boncella, James M., which mentions a compound: 18583-60-3, SMILESS is [BH-](N1N=CC=C1)(N2N=CC=C2)N3N=CC=C3.[K+], Molecular C9H10BKN6, Name: Potassiumtris(1-pyrazolyl)borohydride.

The synthesis of a tris(pyrazolyl)borate-stabilized molybdenum(VI) imido alkylidene complex, TpMo(CHC(Me)2Ph)(NAr)(OTf) (1) [Ar = 2,6-i-Pr2-C6H3, Ph = C6H5, OTf = OSO2CF3], has been achieved by addition of potassium hydridotris(1-pyrazolyl)borate (KTp) to Mo(CHC(CH3)2Ph)(NAr)(OTf)2(DME). Stirring compound 1 over alumina in the presence of H2O gave TpMo(CH2C(Me)2Ph)(NAr)(O) (2). Alternatively, compound 1 was converted to 2 by the addition of CsOH·H2O in THF. A single crystal of [TpMo(NAr)(O)]2O (4) was isolated from a solution of 2. Compounds 2 and 4 have been characterized by x-ray crystallog. and the bonding considerations about the molybdenum atoms are discussed.

Category: piperazines. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: Potassiumtris(1-pyrazolyl)borohydride, is researched, Molecular C9H10BKN6, CAS is 18583-60-3, about Paramagnetic Pyrazolylborate Complexes Tp2M and Tp*2M: 1H, 13C, 11B, and 14N NMR Spectra and First-Principles Studies of Chemical Shifts. Author is Pyykkonen, Ari; Feher, Robert; Kohler, Frank H.; Vaara, Juha.

The paramagnetic pyrazolylborates Tp2M and Tp*2M (M = Cu, Ni, Co, Fe, Mn, Cr, V) as well as [Tp2M]+ and [Tp*2M]+ (M = Fe, Cr, V) were synthesized and their NMR spectra recorded. The 1H signal shift ranges vary from ~30 ppm (Cu(II) and V(III)) to ~220 ppm (Co(II)), and the 13C signal shift ranges from ~180 ppm (Fe(III)) to ~1150 ppm (Cr(II)). The 11B and 14N shifts are ~360 and ~730 ppm, resp. Both neg. and pos. shifts were observed for all nuclei. The narrow NMR signals of the Co(II), Fe(II), Fe(III), and V(III) derivatives provide resolved 13C,1H couplings. All chem. shifts were calculated from 1st-principles on a modern version of Kurland-McGarvey theory which includes optimized structures, zero-field splitting, and g tensors, as well as signal shift contributions. Temperature dependence in the Fe(II) spin-crossover complex results from the equilibrium of the ground singlet and the excited quintet. The authors illustrate both the assignment and anal. capabilities, as well as the shortcomings of the current computational methodol. The large 1H, 13C, 11B, and 14N NMR signal shifts of paramagnetic complexes with popular Tp ligands are reproduced by 1st-principles calculations This supports the signal assignment and thus efficient characterization of the compounds Hints to the best-suited central-metal ions and NMR nuclei as well as information on underlying g factors, zero-field splittings, and structures are provided. The spin crossover of Tp2Fe is analyzed.
