(2,4-Dichlorobenzoylmethyl)triphenylphosphonium chloride

“…As in other triphenylphosphonium salts (Mariyatra et al, 2003), there are some intermolecular and intramolecular CÐ HÁ Á ÁO and CÐHÁ Á ÁCl hydrogen bonds ( Table 2). The packing is shown in Fig.…”

Structural and computational study of some new nano-structured Hg(ii) compounds: a combined X-ray, Hirshfeld surface and NBO analyses

“…7 CH/X (X ¼ Cl, Br and I) interactions are another non-conventional hydrogen bonding that stabilizes supramolecular chains in some solid state structures. [8][9][10] CH/p hydrogen bonds are the other weak intermolecular interactions that may conduct the structure to special supramolecular structure. 11 Non-covalent S/X (X ¼ O, N, S, C, etc.)…”

Bidentate coordination of a diketo phosphorus ylide: synthesis and structure of [(C6H5)3PC(COCH3)(COC6H5)-κO,O′]UO2(NO3)2

“…Examples include ylide complexes of Pd(II) [4], Pt(II) [5], Rh(I) [6], Ti(IV), Zr(IV), Hf(IV) [7], Cu(II) [8], Hg(II) [9], W(0) [10], Ag(I) [11], Au(I), Au(II) and Au(III) [12]. In addition, phosphonium salt [13] and metalate [14] formations often interfere in their reactions with hydrated metal salts. The monoketo ylides and C,C-disubstituted ylides differ in their reactivity towards metal derivatives, for e.g., O-coordination of the monoketo ylide was observed with trimethyltin chloride [15], whereas the reaction of Ph 3 PC(COCH 3 )(COPh) (ABPPY) with the same tin substrate did not yield the direct complexation product but led to decomposition to [17].…”
