This article discusses synthesis of two heterometallic complexes [Cu(phen)2Fe(CN)5(NO)]·2H2O (1) and [Cu(phen)3][Fe(CN)5(NO)]·2H2O (2) prepared from zerovalent copper, sodium nitroprusside (SNP), ammonium thiocyanate in dimethylformamide (DMF) solution of 1,10-phenanthroline (phen). Single crystal X-ray analysis revealed that compound 1 has a molecular structure with [Cu(phen)2]2+ and [Fe(CN)5NO]2– blocks joined through a bridging CN group of nitroprusside whereas compound 2 consists of a separate [Cu(phen)3]2+ cation and [Fe(CN)5NO]2– anion. The magnetic behaviour of compound 1 is paramagnetic. Compound 1 displays photo-induced transition to the metastable state SI after irradiation with blue light, what was proved by a low-frequency shift of ν(N–O) bands.
