Crystal structure of bis(μ2-4-tert-butyl-2-formylphenolato)-1:2κ3 O 1,O 2:O 1;3:4κ3 O 1,O 2:O 1-bis(4-tert-butyl-2-formylphenolato)-2κ2 O 1,O 2;4κ2 O 1,O 2-di-μ3-methoxido-1:2:3κ3 O;1:3:4κ3 O-di-μ2-methoxido-1:4κ2 O;2:3κ2 O-tetracopper(II)
The structure of the title compound, [Cu4(CH3O)4(C11H13O2)4], consists of dimeric dinuclear copper(II) complexes oriented around a centre of inversion. Within each dinuclear fragment, the two Cu(II) atoms are in a distorted square-planar coordination sphere. Two neighbouring fragments are linked by four apical Cu-O contacts, yielding an overall square-pyramidal coordination environment for each...
متن کاملCrystal structure of (2,2′-bipyridine-κ2 N,N′)bis(3,5-di-tert-butyl-o-benzoquinonato-κ2 O,O′)ruthenium(II)
In the title mononuclear complex, [Ru(C14H20O2)2(C10H8N2)], the RuII ion has a distorted octa-hedral coordination environment defined by two N atoms of the chelating 2,2'-bi-pyridine ligand and four O atoms from two 3,5-di-tert-butyl-o-benzo-quinone ligands. In the crystal, the complex mol-ecules are linked by inter-molecular C-H⋯O hydrogen bonds and π-π stacking inter-actions between the 2,2'-...
متن کاملCrystal structure of 2,4-di-tert-butyl-6-(hydroxymethyl)phenol
The title compound, C15H24O2, is an example of a phenol-based pendant-arm precursor. In the mol-ecule, the phenol hy-droxy group participates in an intra-molecular O-H⋯O hydrogen bond with the pendant alcohol group, forming an S(6) ring. This ring adopts a half-chair conformation. In the crystal, O-H⋯O hydrogen bonds connect mol-ecules related by the 31 screw axes, forming chains along the c ax...
متن کاملCrystal structure of (Z)-4-methylbenzyl 3-[1-(5-methylpyridin-2-yl)ethylidene]dithiocarbazate1
In the title dithiocarbazate compound, C17H19N3S2, the central CN2S2 residue is essentially planar (r.m.s. deviation = 0.0288 Å) and forms dihedral angles of 9.77 (8) and 77.47 (7) with the substituted-pyridyl and p-tolyl rings, respectively, indicating a highly twisted molecule; the dihedral angle between the rings is 85.56 (8) . The configuration about the C N bond is Z, which allows for the ...
