Abstract

In the title compound, [Hg(C6H5)(C13H9F2N4S)]·0.5CH2Cl2, the Hg(C6H5) units are twisted out of the planes of the thio­carbazo­nate ligands by 61.49 (10) and 67.79 (11)° in the two complex mol­ecules comprising the asymmetric unit. Important geometrical parameters include Hg—C = 2.079 (4) and 2.087 (4) a, Hg—S = 2.3869 (10) and 2.3889 (11) a, and C—Hg—S = 166.42 (12) and 168.09 (13)°. Weak intramolecular Hg—N bonding inter­actions of 2.589 (4) and 2.626 (4) a are observed. In the crystal, C—H⋯Cl, C—H⋯F, C—H⋯N, C—H⋯π and π-π [centroid-centroid distances = 3.648 (3) and 3.641 (3) a] inter­actions, create parallel planes along [101].

Abstract

Compound [Ir(C8H12)(C51H45P4)]Cl2 or [Ir(cod)(CH(dppm)2-κ3 P,C,P)]Cl2 (1a), was obtained from [IrCl(cod)]2 and the carbodi­phospho­rane (CDP) salt [CH(dppm)2]Cl [where cod = cyclo­octa-1,5-diene and dppm = bis­(di­phenyl­phosphino)methane]. Treatment of 1a with thallium(I) tri­fluoro­methane­sulfonate [Tl(OTf)] and subsequent crystallization gave complex [Ir(C8H12)(C51H45P4)](OTf)2·CH3CO2C2H5·CH2Cl2 or [Ir(cod)(CH(dppm)2-κ3 P,C,P)](OTf)2·CH3CO2C2H5·CH2Cl2 (1b) [systematic name: (cyclo­octa-1,5-diene)(1,1,3,3,5,5,7,7-octa­phenyl-1,7-diphospha-3,5-di­phospho­niaheptan-4-yl)iridium(I) bis­(tri­fluoro­methane­sulfonate)-ethyl acetate-di­chloro­methane (1/1/1)]. This five-coordinate iridium(I) complex cation adopts a trigonal-bipyramidal geometry with the CDP carbon and one cod double bond in axial sites. Compound 1b represents the first example of a non-meridional coordination of the PCP pincer ligand [CH(dppm)2]+ with a P—Ir—P angle of 98.08 (2)°. Compound 2, [IrCl2H(C51H44P4)]·(CH3)2CO or [IrCl2H(C(dppm)2-κ3 P,C,P)]·(CH3)2CO [systematic name: di­chlorido­hydrido(1,1,3,3,5,5,7,7-octa­phenyl-1,5λ5,7-triphospha-3-phospho­niahept-4-en-4-yl)iridium(III) acetone monosolvate], crystallizes as an acetone monosolvate. It is a six-coordinate IrIII coordination compound. Here, the PCP pincer ligand is coordinated in a meridional manner; one chlorido ligand is positioned trans to the carbon donor, the remaining two coordination sites being occupied by the second chlorido and a hydrido ligand trans to each other. Complex 3, [IrCl2H(C51H45P4)]Cl·5H2O or [IrCl2H(CH(dppm)2-κ3 P,C,P)]Cl·5H2O [systematic name: di­chlorido­hydrido(1,1,3,3,5,5,7,7-octa­phenyl-1,7-diphospha-3,5-di­phospho­niaheptan-4-yl)iridium(III) chloride penta­hydrate], represents the conjugate CH acid of 2. The ligand [CH(dppm)2]+ is coordinated in a meridional manner. In the cationic six-coordinate IrIII complex 4, [IrClH(CO)(C51H44P4)]Cl·2CH3OH·H2O or [IrClH(CO)(C(dppm)2-κ3 P,C,P)]Cl·2CH3OH·H2O [systematic name: carbonyl­chlorido­hydrido(1,1,3,3,5,5,7,7-octa­phenyl-1,5λ5,7-triphospha-3-phos­pho­niahept-4-en-4-yl)iridium(III) chloride-methanol-water (1/2/1)], the chlorido ligand is found in the plane defined by the Ir center and the meridional PCP ligand; the H and CO ligands are positioned axially to this plane and trans to each other.

Abstract

In this study, the diversity of Pyxine Fr. in China was assessed based on morphological and chemical traits and molecular data are inferred from ITS and mtSSU sequences. Nineteen species were recognised, including three that are new to science (i.e. P.flavicans M. X. Yang & Li S. Wang, P.hengduanensis M. X. Yang & Li S. Wang and P.yunnanensis M. X. Yang & Li S. Wang) and three records new to China were found (i.e. P.cognata Stirt., P.himalayensis Awas. and P.minuta Vain.). Pyxineyunnanensis is diagnosed by the small size of the apothecia, a white medulla of the stipe and the presence of lichexanthone. Pyxineflavicans is characterised by broad lobes, a pale yellow medulla of the stipe and the presence of atranorin. Pyxinehengduanensis can be distinguished by its pale yellow medulla, marginal labriform soralia and the absence of atranorin. Detailed descriptions of each new species are presented, along with a key to the known species of Pyxine in China.
