The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: Potassiumtris(1-pyrazolyl)borohydride, is researched, Molecular C9H10BKN6, CAS is 18583-60-3, about Structural characterization and variable temperature 1H NMR of monoporphyrinate samarium(III) and erbium(III) complexes, the main research direction is samarium erbium porphyrinate pyrazolylborate preparation NMR.Category: piperazines.

Two samarium(III) and erbium(III) monoporphyrinate complexes stabilized by anionic hydrotris(pyrazolyl)borate (TpH) were prepared and characterized by elemental anal., UV-visible, IR, and mass spectra. Structural anal. revealed that seven N atoms from porphyrin dianion and TpH- coordinated to the lanthanide ions. The 1H NMR spectra showed Sm3+ has a slight effect on proton chem. shifts, whereas Er3+ has a heavy effect that leads to the up-field and downfield shift of proton chem. shift. The variable temperature 1H NMR reveals that the chem. shifts of protons of all complexes are temperature-dependent.

The reactions of 2 equiv of K[H2B(pz)2], K[HB(pz)3], K[B(pz)4], K[H2B(3,5-Me2pz)2], K[HB(3,5-Me2pz)3], and K[B(3-Mepz)4] with CdCl2 give the resp. [poly(pyrazolyl)borato]2Cd complexes in high yields. A similar reaction with a 1/1 mixture of K[HB(3,5-Me2pz)3] and either K[H2B(pz)2] or K[B(pz)4] yields [HB(3,5-Me2pz)3]Cd[H2B(pz)2] (7) or [HB(3,5-Me2pz)3]Cd[B(pz)4] (8), resp. The solid-state structures of [B(pz)4]2Cd (3), [HB(3,5-Me2pz)3]2Cd (5), and [B(3-Mepz)4]2Cd.2C7H8 (6) were determined crystallog. All 3 complexes show a distorted octahedral arrangement of the N donor atoms, with the Cd atom located on a center of symmetry. For 5, all Cd-N bonding distances are equal, but for 3 and 6, 3 different Cd-N bond distances, with the differences being as large as 0.103 Å for 3, are observed Variable-temperature 1H NMR spectra show that complexes 1, 3, 4, and 6-8 are dynamic in solution For 3, 6, and 8 all of the pyrazolyl rings of the tetrakis(pyrazolyl)borate ligands are equivalent at high temperatures with a 3/1 pattern observed at low temperatures A mechanism that exchanges a coordinated with the noncoordinated pyrazolyl ring for the tetrakis(pyrazolyl)borate ligands is presented to explain these data. For 7 at low temperatures each resonance type for the [HB(3,5-Me2pz)3]- ligand appears as 2 resonances in a 2/1 ratio, resonances that coalesce at higher temperatures The pyrazolyl ring resonances for the [H2B(pz)2]- ligand resonances remain equivalent at low temperatures, indicating a 5-coordinate, square pyramidal arrangement of the N donor atoms. For 8, the resonances for the [HB(3,5-Me2pz)3]- ligand remain equivalent at low temperatures, indicating that the complex in 6-coordinate.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Heteroleptic poly(pyrazolyl)borate derivatives of the lanthanides.

The solid-angle sum of 0.768 is close to the norm for eight-coordination. These structural parameters were compared with those calculated for the previously reported binuclear complex [{Sm[HB(pz)3]2(O2CPh)}2] and estimated for its monomeric counterpart, which is as yet unknown. The use of such data in predicting when complexes of this type will dimerize was assessed. Electronic spectra of the Nd complexes revealed <1% covalency in the metal-ligand bonding and emission spectral data are reported for the Eu and Tb complexes.

COA of Formula: C9H10BKN6. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: Potassiumtris(1-pyrazolyl)borohydride, is researched, Molecular C9H10BKN6, CAS is 18583-60-3, about Electronic Structures of Highly Symmetrical Compounds of f Elements 44 [1].

Author is Apostolidis, Christos; Morgenstern, Alfred; Rebizant, Jean; Kanellakopulos, Basil; Walter, Olaf; Powietzka, Bernhard; Karbowiak, Miroslav; Reddmann, Hauke; Amberger, Hanns-Dieter.

The absorption spectrum of tris[hydrotris(1-pyrazolyl)borato]uranium (UTp3) was run at room and low temperatures From the spectra obtained, a truncated crystal field (CF) splitting pattern could be derived, and simulated by fitting the free parameters of a phenomenol. Hamiltonian achieving an root-mean-square deviation of 37.7 cm-1 for 29 assignments. The parameters used allow the insertion of the Tp ligand into empirical spectrochem., nephelauxetic and relativistic nephelauxetic series of UIII compounds, and the set-up of exptl. based nonrelativistic and relativistic MO schemes of UTp3 in the f range. Using the wavefunctions and eigenvalues of the fit, the exptl. determined temperature dependence (at 1.34-294.4 K) of μ2eff could be reproduced adopting an orbital reduction factor k = 0.99.
