Bis(di-n-propyldithiophosphinato)zinc(II)

A Novel Reactivity Mode for Metal-Activated Dialkylcyanamide Species: Addition ofN,N′-Diphenylguanidine to acis-(R2NCN)2PtIICenter Giving an Eight-Membered Chelated Platinaguanidine

“…It is worth mentioning that five- and six-membered metal chelate rings are the most conventional ring systems in coordination chemistry insofar as they exhibit exceptional stablity , (for general consideration of the chelate effect, see refs − ). However, seven-, − eight- (in particular, having N ∩ N, ,,− P ∩ P, ,− S ∩ S, , Se ∩ Se, O ∩ O, − P ∩ O, and C ∩ O donor centers), − nine-, ,, ten-, eleven-, and twelve-membered and also complexes with trans-spanned ligands and large metallamacrocycles ,− , are also known, albeit they are still unusual rather than common.…”

Molecular architecture and supramolecular association in the zinc-triad 1,1-dithiolates. Steric control as a design element in crystal engineering?

“…The dinuclear motif (III) is adopted by 33 structures, with the majority containing zinc. A total of 15 zinc dithiocarbamates, 20,[31][32][33][34][35][36][37][38][39][40][41][42] one dithiophosphinate 43 and two dithiobenzoates 44 adopt this motif. For cadmium, seven dithiocarbamates [45][46][47][48][49][50][51][52] one dithiophosphate, 53 and three dithiophosphinate [54][55][56][57] compounds conform to this motif albeit with minor modifications for the dithiocarbamate sub-set (see below).…”

Variable Coordination Modes in Dialkyldithiophosphinato Complexes of Group 13 Metals: The X-ray Single Crystal Structures of Tris(diisobutyldithiophosphinato)gallium(III) and -indium(III)

“…Dithiophosphinato complexes have found application as solvent extraction reagents for metals, insectides and pesticides, flotation agents for mineral ores, and additives to lubricant oils and can be used as precursors for use in metal−organic chemical vapor deposition (MOCVD). − The structures of a number of zinc and cadmium complexes of substituted dithiophosphorus ligands of the type (−S 2 PR 2 ), e.g., [Zn(S 2 PR 2 ) 2 ] 2 (R = Et 2, n Pr 2 , i Bu 2 4 ) and [Cd(S 2 PR 2 ) 2 ] 2 (R = Et 2 , − i Bu 2 , Ph 2 ), have been determined by X-ray crystallography. The related indium compounds [In(S 2 PR) 3 ] (R = Me,11a Et,,11b OEt,11c Ph 11a ) are monomeric in the solid state in contrast to the dinuclear formulations seen for the zinc and cadmium species.…”
