“…42 The coupling constants 1 J(Ag-31 P), in conjunction with other physical data, also provide a useful probe for studying changes in molecular structure in solution. Tentatively, it is possible to analyze, as a first approximation, the correlation between 1 J(Ag-P) and h(P-Ag-P) in terms of the hybridization model [43][44][45][46][47] based on the equation given by Pople and Santry. 48 (3).…”

Silver(i)-organophosphane complexes of electron withdrawing CF3- or NO2-substituted scorpionate ligands

New silver(I) complexes have been synthesized from the reaction of AgNO(3), monodentate tertiary phosphanes PR(3) (PR(3) = P(C(6)H(5))(3), P(o-C(6)H(4)CH(3))(3), P(m-C(6)H(4)CH(3))(3), P(p-C(6)H(4)CH(3))(3), PCH(3)(C(6)H(5))(2)) and two novel electron withdrawing ligands: potassium dihydrobis(3-nitropyrazol-1-yl)borate and potassium dihydrobis(3-trifluoromethylpyrazol-1-yl)borate. These compounds have been characterized by elemental analyses, FT-IR, ESI-MS and multinuclear ((1)H, (19)F and (31)P) NMR spectroscopy. Solid state structures of the potassium salts K[H(2)B(3-(NO(2))pz)(2)] and K[H(2)B(3-(CF(3))pz)(2)] have been reported. They form polymeric networks due to intermolecular contacts of various types between the potassium ion and atoms of the neighboring molecules. The silver adducts [H(2)B(3-(NO(2))pz)(2)]Ag[P(C(6)H(5))(3)](2) and [H(2)B(3-(NO(2))pz)(2)]Ag[P(p-C(6)H(4)CH(3))(3)] have pseudo tetrahedral and trigonal planar silver sites, respectively. The bis(pyrazolyl)borate ligand acts as a kappa(2)-N(2) donor. The nitro-substituents are coplanar with the pyrazolyl rings in all these adducts indicating efficient electron delocalization between the two units. The [H(2)B(3-(CF(3))pz)(2)]Ag[P(C(6)H(5))(3)] complex has been obtained from re-crystallization of {[H(2)B(3-(CF(3))pz)(2)]Ag[P(C(6)H(5))(3)](2)} in a dichloromethane-diethyl ether solution; it is a three-coordinate, trigonal planar silver complex.

“…Such a positive correlation between P-Ag-P angle and solution 1 J(Ag-31 P) data has been previously observed for other silver complexes. [43][44][45] For a given phosphane, the Ag-P bond length is expected to increase as the P-Ag-P angle decreases. However, changes in the Ag-P distance results in only small changes in 1 J(Ag-P).…”

This review covers the crystallographic data for dimeric tin compounds with one other metal atom centre, following the pattern of the previous reviews on tin coordination and organometallic compounds. Over two hundred and forty such derivatives have been characterised, twenty three with a non-transition heterometal atom, one with an actinide metal and the rest with a transition metal atom. The predominant geometries of the tin and the heteroatom are discussed along with the relationships between atom size, bond distances and bond angles. The occurrences of direct metal-metal bonds, and examples of isomerism are illustrated CONTENTS 0. ABBREVIATIONS 1. DIMERIC COMPOUNDS 2.1 Α-Group (Non-Transition) MetalsCrystallographic and structural data for some twenty three tin heterometallic compounds with sub-group A. or non-transition metals, are summarised in Table 1. These are listed in their Periodic Group order, with the typical metals of each group first, and then the Sn-M distance. The first eight derivatives contain tin with lithium [6][7][8][9][10][11][12][13], with the tin in the +2 oxidation state and lithium in its usual +1 oxidation state.

Here, three Ph(Bu')CN ligands bridge the lithium and tin atoms via their Ν atoms, with Sn-N-Li bridge angles of 81,5( 1A slightly longer Sn-Li distance of 278.4(4) pm is found in a cyclometalated dimer [7] leid together by bridging Ο atoms of three 2,6diphenylphenoxide ligands, with mean Sn-O-Li bridge angles of 84.5(2)°.Two crystallographically independent molecules within the asymmetric units of Ph3SnLi(pmdeta) [8] differ essentially by degree of distortion. While the Sn(II) atom is coordinated by three phenyl groups, the Li(I) atom utilises the tridentate pmdeta moiety. Four coordination is accomplished by each metal via a direct Sn-Li bond of 286.1(7) and 288.2(7) pm in the respective distortion isomers. Another colourless derivative [9] also contains two crystallographically independent molecules. A direct Sn-Li bond of 289(4) and 297(5) pm, respectively, hold together the N3Sn and LiCb moieties.A lithium atom in the next derivative [ 10] ties two amido groups together to generate an N-donor arrangement which forms part of the N3Sn pyramid, one corner of which is the Sn(II) atom. The structure of a red derivative [11] involves a {(Me3Si)3}2Sn unit coordinated to a LiCl(thf)3 moiety via a chlorine bridge. The tricoordinated Sn(II) atom is also at one corner of a pyramid. A tricoordinated tin atom is also found in a metallocyclic arrangement [12] of a four membered (Sn-P-Li-P) ring with average Sn-P-Li angles of 89.5(7)°.The Sn centre in a sandwich style complex [13] is attached to two distorted η-cp ligands and the planar Ν atom of a (Me3Si)2N group, as seen in Figure 1. The tin atom has a distorted pyramidal geometry, and the cp(Y) ligand h...
