Redetermination of bis(O,O′-diethyl dithiophosphato-κ2 S,S′)nickel(II)
The centrosymmetric title complex, [Ni{S(2)P(OC(2)H(5))(2)}(2)], has been redetermined using area-detector data. The central Ni(S(2)P)(2) core is essentially planar and confirms the early results of McConnell & Kastalsky [Acta Cryst. (1967), 22, 853-859] based on multiple film technique data. In the title structure, the standard uncertainty values are approximately seven times lower and all H-a...
متن کاملBis(O,O′-diphenethyl dithiophosphato-κ2 S,S′)bis(4-methylpyridine-κN)nickel(II)
The title complex, [Ni(C(16)H(18)O(2)PS(2))(2)(C(6)H(7)N)(2)], exhibits a roughly octa-hedral coordination geometry. The Ni(II) atom lies on an inversion centre and is coordinated by four S atoms of O,O'-diphenethyl dithio-phosphate mol-ecules and two N atoms of 4-methyl-pyridine mol-ecules. Important geometric data include Ni-N = 2.100 (3) Å, and Ni-S = 2.5101 (10) and 2.4772 (11) Å.
متن کاملDirect Aldehyde C-H Arylation and Alkylation via the Combination of Nickel, Hydrogen Atom Transfer, and Photoredox Catalysis.
A mechanism that enables direct aldehyde C-H functionalization has been achieved via the synergistic merger of photoredox, nickel, and hydrogen atom transfer catalysis. This mild, operationally simple protocol transforms a wide variety of commercially available aldehydes, along with aryl or alkyl bromides, into the corresponding ketones in excellent yield. This C-H abstraction coupling technolo...
متن کاملcatena-Poly[[bis(O,O′-diisopropyl dithiophosphato-κ2 S,S′)nickel(II)]-μ-bis(4-pyridylmethylene)diazane-κ2 N:N′]
The Ni atom in the title linear supra-molecular polymer, [Ni(C(6)H(14)O(2)PS(2))(2)(C(12)H(10)N(4))](n), exists within a trans-N(2)S(4) octa-hedral donor set defined by two symmetrically coordinating dithio-phosphate ligands and pyridine N atoms derived from two bridging bis-(4-pyridylmethyl-ene)diazane ligands. The Ni atom lies on a centre of inversion and the bis-(4-pyridylmethyl-ene)diazane ...
متن کاملBis[O-methyl (4-ethoxyphenyl)dithiophosphonato-κ2 S,S′]nickel(II)
In the title compound, [Ni(C9H12O2PS2)2], the Ni(II) atom resides on an inversion center and is coordinated by four S atoms [Ni-S = 2.2328 (4) and 2.2455 (3) Å] in a distorted square-planar geometry [S-Ni-S = 88.443 (13) and 91.557 (13)°]. In the crystal, mol-ecules related by translation in [110] are linked into chains via weak C-H⋯O inter-actions. The crystal packing exhibits short inter-mole...
