Reaction of N(CH2PPh2)3 with (CH3CN)3M o(CO)3 leads to N(CH 2PPh2)3M o(CO)3 (2). The cationic complex [HN(CH2PPh2)3Mo(CO)3]+ (3) is obtained by protonating the N atom of 2 with aqueous HBF4. The spectroscopic and structural properties of 2 and the cation 3 are compared. The results indicate an interaction of the ligand N atom and the Mo atom through space over more than 350 pm. It is shown from IR data that 2

 Title    Darstellung und spektroskopische Charakterisierung von Natriumpentacyano(phosphan/phosphit)ferraten(III) Preparation and Spectroscopic Characterization of Sodium Pentacyano(phosphane/phosphite)ferrates(III) Hidenari Inoue3, Satomi Osone3  
 Abstract    Sodium pentacyanoferrates(III) of the type Na2[Fe(CN)5L] (L = phosphane or phosphite) have been prepared from sodium pentacyanoferrates(II), Na3[Fe(CN)5L], by bromine oxidation and characterized by Mössbauer, IR, and electronic spectroscopy. Isomer shifts and quadrupole splittings lie within the range commonly found in low-spin iron(III) complexes. A linear correlation was found between isomer shifts and CN stretching and Fe-CN bending frequencies, respectively. The spectroscopic parameters show that the d^-d^ back bonding o f the Fe-P bonds is synergetically strengthened with increasing a donor capability of the phosphorus ligands.

 Title    Heteronukleare Komplexverbindungen mit M etall-M etall-Bindungen, V [1]  
 Abstract    Umsetzungen mit [(NH3)2CuCo(CO)4l: Synthese und Struktur von |(PPh3)2CuCo(CO)4|, [Cu{P(OM e)3}4][Cu{Co(CO)4}2] und (Ph3P)2N |C u{C o(C O)4}2] H eteronuclear C o-ordination Com pounds with M e ta l-Metal-Bonds, V [1] Reactions with [(NH3)2CuCo(CO)4]: Synthesis and Structure of [(PPh3)2CuCo(CO)4], [Cu{ P(OM e)3}4][Cu{Co(CO)4}2] and (Ph3P)2N[Cu{Co(CO)4}2] The heteronuclear carbonyl complex [(NH3)2CuCo(CO)4] 1 reacts with the phosphane li­ gands PPh3, PEt3 and P(OMe)3. A dinuclear complex, [(PPh3)2CuCo(CO)4] 2, is formed with PPh3, while trinuclear anionic [Cu{Co(CO)4}2]~ species are formed with the other phosphane ligands. The crystal structure of 2 (C u-C o = 255.2(2) pm) and the structures of two com­ pounds with trinuclear anions, [Cu{P(OMe)3}4][Cu{Co(CO)4}^] 3 (C u-C o = 232.64(8) and 233.10(8) pm) and PPN[Cu{Co(CO)4}2] 6 (C u-C o = 238.1(l)"and 234.3(1) pm), have been determined by X-ray crystallography. The angle Cax-C o -C eq of tetracarbonyl cobalt com­ pounds (i.e. the deviation from tetrahedral geometry) depends on the charge of the Co(CO)4 fragment, as calculated with the electronegativity equalization scheme of Bratsch (J. Chem. Ed. 61, 588 (1984)).
