| Abstract: | Different reactions of BrC(CN)3 with metal bromides (MBr4; M = Sn, Ti, Zr), metal organyles (SnR4, MR2 (R = C2H5, C6H5; M = Zn, Cd), C6H5HgBr) and with phosphorus tribromide are reported. These reactions lead to the formation of new compounds of the types MBr3NCC(CN)2, R3MNCC(CN)2, RMNCC(CN)2 and PBr4NCC(CN)2, respectively. The structures of the new compounds are discussed, using results of infrared spectroscopic measurements. Mostly the pseudohalide group C(CN)3 is bonded to the metal via the nitrogen of a cyano group. Unsolubility and IR spectra are characterizing the compounds of the types MBr3NCC(CN)2 and RMNCC(CN)2 as coordination polymers. IIb-metal derivatives form pyridine complexes [RMNCC(CN)2(C5H5N)2]. |
