"μ-(1-phenyl-3,4-dimethylphosphole)-μ-(1-tert-butyl-3,4-dimethylphosphole)-bis(dicarbonyliron)" is a complex organophosphorus compound consisting of two different phosphole rings, each coordinated to a central iron atom. The phosphole rings are substituted with different groups: one with a phenyl group and the other with a tert-butyl group, both having dimethyl substituents at the 3,4-positions. The iron center is bonded to two carbonyl ligands, which are linear, two-electron donor ligands. μ-(1-phenyl-3,4-dimethylphosphole)-μ-(1-tert-butyl-3,4-dimethylphosphole)-bis(dicarbonyliron) is of interest in organometallic chemistry due to its unique structure and potential applications in catalysis and materials science. It represents a class of compounds that can exhibit interesting electronic properties and reactivity due to the combination of phosphorus-containing heterocycles and transition metal centers.

Check Digit Verification of cas no

The CAS Registry Mumber 77611-25-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,6,1 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 77611-25:
(7*7)+(6*7)+(5*6)+(4*1)+(3*1)+(2*2)+(1*5)=137
137 % 10 = 7
So 77611-25-7 is a valid CAS Registry Number.

Bimetallic sandwiches based upon phosphole ligands

Santini, Catherine C.,Fischer, Jean,Mathey, Fran?ois,Mitschler, André

, p. 2848 - 2852 (2008/10/08)

The reaction of a phosphole (L) with a σ,π complex L'Fe2(CO)n (L′ = another phosphole; n = 6 or 7) gives the metallic sandwich L[Fe2(CO)4]L′. A heterobimetallic sandwich is also obtained when L′FeMo(CO)8 is the starting compound. The X-ray crystal structure of the complex with L = L′ = 1-phenyl-3,4-dimethylphosphole has been determined. Crystal data: monoclinic, C2/c, with a = 14.334 (1) A?, b = 12.375 (1) A?, c = 16.470 (1) A?, β = 112.62 (1)°. The two phosphole rings adopt a head to tail disposition and are strongly folded. Very large 31P-31P NMR coupling suggests a direct through-space interaction between the nonbonded phosphorus and iron atoms.
