Crystal structure of a homoleptic zinc(II) complex based on bis-(3,5-diiso-propyl-pyrazol-1-yl)acetate.

ABSTRACT: Deprotonation of the methyl-ene group in bis-(3,5-diiso-propyl-pyrazol-1-yl)methane with nBuLi and reaction with carbon dioxide yields lithium bis-(3,5-diiso-propyl-pyrazol-1-yl)acetate (1). Treatment of 1 with ZnCl₂ results in the com-pound bis-[bis-(3,5-diiso-propyl-pyrazol-1-yl)acetato]-zinc(II), [Zn(C₂₀H₃₁N₄O₂)₂] (2), whose structure has monoclinic (P2₁/c) symmetry. The Zn^II ion resides on an inversion center and is coordinated by two bis-(3,5-diiso-propyl-pyrazol-1-yl)acetate (bdippza) ligands. Each ligand facially coordinates the zinc center via ?³N,N',O coordination modes to form a distorted octa-hedral complex with four pyrazole N atoms in the basal plane and two carboxyl-ate O atoms in the axial sites.

Crystal structure of bis-[1,3-bis-(2,6-diiso-propyl-phen-yl)imidazol-2-yl-idene]silver(I) chloride tetrahydro-furan monosolvate.

Project description:In the title salt, [Ag(C27H36N2)2]Cl·C4H8O, the Ag(I) atom is coordinated by two 1,3-bis-(2,6-di-methyl-phen-yl)imidazol-2-yl-idene ligands. The imidazole rings are inclined to one another by 46.69?(13)° and the benzene rings in each ligand are almost normal to the imdazole ring to which they are attached, with dihedral angles varying from 82.39?(13) to 88.27?(12)°. There are C-H?? inter-actions present in the cation, involving the two ligands, and the solvent mol-ecule is linked to the cation via a C-H?O hydrogen bond. In the crystal, mol-ecules are linked by trifurcated C-H?(Cl,Cl,Cl) hydrogen bonds, forming slabs parallel to (101). One isopropyl group is disordered over two sets of sites with an occupancy ratio of 0.447?(17):0.553?(17) and the THF mol-ecule is disordered over two positions with an occupancy ratio of 0.589?(6):0.411?(6).

Crystal structure of N,N'-bis-(diiso-propyl-phosphan-yl)-4-methyl-pyridine-2,6-di-amine.

Project description:In the mol-ecule of the title compound, C18H35N3P2, the methyl-pyridine-2,6-di-amine moiety is almost planar, with a maximum deviation of 0.0129?(9)?Å for one of the amine N atoms. Whereas one of the P atoms is co-planar with this mean plane [deviation = 0.0158?(10)?Å], the other P atom is considerably displaced out of the mean plane by 0.5882?(10)?Å. In the crystal, no directional intermolecular interactions beyond van der Waals contacts could be identified.

Crystal structure of bis-(diiso-propyl-ammonium) molybdate.

Project description:The organic-inorganic title salt, (C6H16N)2[MoO4] or ( i Pr2NH2)2[MoO4], was obtained by reacting MoO3 with diiso-propyl-amine in a 1:2 molar ratio in water. The molybdate anion is located on a twofold rotation axis and exhibits a slightly distorted tetra-hedral configuration. In the crystal structure, the diiso-propyl-ammmonium ( i Pr2NH2)+ cations and [MoO4]2- anions are linked to each other through N-H?O hydrogen bonds, generating rings with R 12 12(36) motifs that give rise to the formation of a three-dimensional network. The structure was refined taking into account inversion twinning (ratio of ca 4:1 between the two domains).

Crystal structure of [bis-(2,6-diiso-propyl-phen-yl) phosphato-?O]tris-(methanol-?O)lithium methanol monosolvate.

Project description:Crystals of the title compound, [Li{OOP(O-2,6-(i)Pr2C6H3)2}(CH3OH)3]·CH3OH or [Li(C24H34O4P)(CH3OH)3]·CH3OH, have been formed in the reaction between HOOP(O-2,6-(i)Pr2C6H3)2 and LiOH in methanol. The title compound is of inter-est as it represents the first reported crystal structure of the family of lithium phosphate diesters. The {Li(CH3OH)3[O2P(O-(i)Pr2C6H3)2]} unit displays the Li atom in a slightly distorted tetra-hedral coordination environment and exhibits one intra-molecular O-H?O hydrogen bond between a coordinating methanol mol-ecule and the terminal non-coordinating O atom of the phosphate group. The unit is connected with two non-coordinating methanol mol-ecules through two inter-molecular O-H?O hydrogen bonds, and with a neighbouring unit through two other O-H?O inter-actions. These inter-molecular hydrogen bonds lead to the formation of infinite chains along [100]. There are no significant inter-actions between the chains.

Crystal structure of 2-azido-1,3-bis-(2,6-diiso-propyl-phen-yl)-1,3,2-di-aza-phospho-lidine.

Project description:The title compound, C26H38N5P, was synthesized by reacting 2-chloro-1,3-bis-(2,6-diiso-propyl-phen-yl)-1,3,2-di-aza-phospho-lidine with sodium azide and a catalytic amount of lithium chloride in tetra-hydro-furan. The title compound is the first structurally characterized 2-azido-1,3,2-di-aza-phospho-lidine and exhibits a P atom in a trigonal pyramidal geometry. The azide P-N bond length of 1.8547?(16)?Å is significantly longer than the P-N separations for the chelating di-amine [P-N = 1.6680?(15) and 1.6684?(14)?Å]. The sterically hindered 2,6-diiso-propyl-phenyl groups twist away from the central heterocycle, with dihedral angles between the central heteocyclic ring and benzene rings of 76.17?(10) and 79.74?(9)°. In the crystal, a weak C-H?N link to the terminal N atom of the azide group leads to [100] chains.

[Bis(2,6-diiso-propyl-phen-yl) phosphato-κO]pentakis-(methanol-κO)manganese bis-(2,6-diiso-propyl-phen-yl) phosphate methanol tris-olvate.

Project description:The title compound, [Mn(C24H34O4P)(CH3OH)5](C24H34O4P)·3CH3OH, was formed in the reaction between a hydrate of a manganese(II) salt [either Mn(NO3)2(H2O)6 or MnCl2(H2O)4] with a methanol solvate of lithium bis-(2,6-diiso-propyl-phen-yl) phosphate, {Li[OOP(O-2,6- i Pr2C6H3)2]·(CH4O)3}·CH4O, in methanol. The structure has monoclinic (Cc) symmetry at 150 K. The complex consists of an [Mn{OOP(O-2,6- i Pr2C6H3)2}(CH3OH)5]+ cation, an [OOP(O-2,6- i Pr2C6H3)2]- anion and three non-coordinating methanol mol-ecules. The anion demonstrates disorder of an isopropyl group [occupancy ratio is 0.57 (4):0.43 (4)]. The di-aryl-phosphate ligand in the cation exhibits a κ1 O terminal coordination mode. The Mn atom is in a nearly unperturbed octa-hedral environment. The [Mn{OOP(O-2,6- i Pr2C6H3)2}(CH3OH)5]+ cation exhibits one intra-molecular O-H⋯O bond, and is coordinated via two inter-molecular O-H⋯O hydrogen bonds to the [OOP(O-2,6- i Pr2C6H3)2]- anion. The cations, anions and non-coordinating methanol mol-ecules are linked into infinite chains along the c-axis direction via 0-H⋯O hydrogen bonding. The complex is of inter-est as a possible inhibitor for the thermal decomposition of polydi-methyl-siloxane. The crystal studied was refined as an inversion twin with a domain ratio of 0.47 (3):0.53 (3).

Crystal structure of bis-{(3,5-di-methyl-pyrazol-1-yl)di-hydro-[3-(pyridin-2-yl)pyrazol-1-yl]-borato}iron(II).

Project description:The structure determination of [Fe(C13H15BN5)2] was undertaken as part of a project on the modification of the recently published spin-crossover (SCO) complex [Fe{H2B(pz)(pypz)}2] (pz = pyrazole, pypz = pyridyl-pyrazole). To this end, a new ligand was synthesized in which two additional methyl groups are present. Its reaction with iron tri-fluoro-methane-sulfonate led to a pure sample of the title compound, as proven by X-ray powder diffraction. The asymmetric unit consists of one complex mol-ecule in a general position. The FeII atom is coordinated by two tridentate N-binding {H2B(3,5-(CH3)2-pz)(pypz)}- ligands. The Fe-N bond lengths range between 2.1222?(13) and 2.3255?(15)?Å, compatible with FeII in the high-spin state, which was also confirmed by magnetic measurements. Other than a very weak C-H?N non-classical hydrogen bond linking individual mol-ecules into rows extending parallel to [010], there are no remarkable inter-molecular inter-actions.

Project description:In the title compound, C(12)H(16)N(4)O(2), the dihedral angle between the two pyrazole rings is 78.17?(7)°. Inter-molecular O-H?N hydrogen bonds link the mol-ecules into one-dimensional chains along the c axis.
