KU X-ray photoelectron (ESCA) ,qrectra of the Co 2p levels have been obtained in fnrns-and ci%[Co(NHa)&a ] Cl isomers\_ It is observed that these compounds slowly decompose under X-ray irradiation. A procedure is employed to record real spectra for both the trans and cis isomers without any sighican
Diammine nickel(II) halides, Ni(NH 3 ) 2 X 2 (X โซุโฌ Cl, Br, I), were prepared by decomposition of the corresponding hexaammines at 1203C in dynamical vacuum. Their crystal structures are of the Cd(NH 3 ) 2 Cl 2 type (99 -type::, space group Cmmm, Z โซุโฌ 2): for Ni(NH 3 ) 2 Cl 2 , a โซุโฌ 8.019 A s , b
The crystal structures of Ni(NCNH 2 ) 4 Cl 2 and Co(NCNH 2 ) 4 Cl 2 , the first complexes with cyanamide as a neutral ligand, have been determined from single crystal data (Im3m, Z = 6, a = 1259.3(2) pm, R 1 = 0.0245 for Ni(NCNH 2 ) 4 Cl 2 and a = 1266.3(2) pm, R 1 = 0.0241 for Co(NCNH 2 ) 4 Cl 2 ;
