The following complexes [{Cu(ept)}3{Cr(CN)6}2]ź5H2O, [{Cu(hatce)}3{Cr(CN)6}2]ź ź15H2O, [{Cu(hatco)}3{Cr(CN)6}2]ź14H2O, [{Cu(ept)}3{Co(CN)6}2]ź5H2O, [{Cu(hatce)}3{Co(CN)6}2]ź18H2O and [{Cu(medpt)}3{Co(CN)6}2]źH2O (ept = N-(2-amino ethyl)-1,3-propandiamine, hatce = 1,3,6,10,12,15-hexaaza tricyclo [13.3.1.16,10]eicosane, hatco = 1,3,6,9,11,14-hexaaza tricyclo[12.2.1.16,9]octadecane and medpt = N,N-bis-(3-aminopropyl)methylamine) have been synthesized by the reactions of Cu(ClO4)2ź6H2O or Cu(NO3)2ź3H2O and ept or medpt, or [Cu(hatce)](ClO4)2ź2H2O and [Cu(hatco)Cl]ClO4źH2O, and K3[Cr(CN)6] or K3[Co(CN)6] in aqueous solution, respectively. All the compounds have been characterized by elemental analyses, IR and UV-Vis spectroscopies and magnetic measurements and the three selected complexes were studied using thermal analysis. The crystal structure of [{Cu(ept)}3{Co(CN)6}2]ź źH2O has been determined by single-crystal X-ray analysis – the studied compound can be for mulated as [{Cu(ept)}6{Co(CN)6}3][Co(CN)6]ź2H2O. The copper atom is five-coordinated by two cyanide-nitrogen and three ept-nitrogen atoms, in a distorted square-pyramidal arrangement. The structure of the other complexes with cyanide bridges between hexacoordinated chromium(III) (S = 3/2) or cobalt(III) (S = 0) and penta- or hexacoordinated copper(II) (S = 1/2) is proposed.

Ni(II) dithiocarbamates with AsI3 or SbI3 as ligands of the composition [Ni(hmidtc)2(AsI3)] (1), [Ni(bzbutdtc)2(AsI3)] (2), [Ni(bzbutdtc)2(SbI3)]_2CHCl3 (3), [Ni(bz2dtc)2(AsI3)] (4), [Ni(bz2dtc)2(SbI3)]_CS2 (5), [Ni(hmidtc)2(AsI3)2]_CHCl3 (6), [Ni(hmidtc)2(SbI3)2] (7) and [Ni(cetdtc)2(AsI3)2] (8), (hmidtc = hexamethyleneiminedithiocarbamate, bzbutdtc = benzylbutyldithiocarbamate, bz2dtc = dibenzyldithiocarbamate, cetdtc = cyclohexylethyldithiocarbamate, dtc = S2CN-) have been synthesized. The complexes have been characterized by elemental analyses, thermal analysis, IR and UV/VIS spectroscopies, magnetochemical and conductivity measurements as square-pyramidal (1-5) and octahedral (6-8) complexes. X-ray analysis of [Ni(bz2dtc)2(AsI3)] and [Ni(bz2dtc)2(SbI3)]_CS2 confirmed square-pyramidal arrangement around nickel in both complexes with the NiS4As and NiS4Sb chromophore, respectively.

A binuclear diamagnetic Ni(II) dithiocarbamates with 1,6-bis(diphenylphosphino)hexane (dpph) as a bidentate bridging P,P-ligand of composition [Ni2(_-dpph)(hmidtc)2X2] (hmidtc = hexamethyleneiminedithiocarbamate, dtc = S2CN-, X = Cl, Br, I, ClO4, NCS); [Ni2(_-dpph)(cetdtc)2X2] (cetdtc = cyclohexylethyldithiocarbamate, X = Cl, Br, I, NCS) and also the mononuclear diamagnetic complex [Ni(cetdtc)(dpph)]ClO4_2H2O have been synthesized. The complexes have been studied by elemental analysis, IR and UV-VIS spectroscopy, thermal analysis, magnetochemical and conductivity measurements. X-ray structural analysis was solved for the [Ni2(_-dpph)(hmidtc)2Br2]_2CHCl3 and confirmed the presence of two NiS2PBr chromophores bonded by the P-donor atoms of 1,6-bis(diphenylphosphino)hexane.

Ni(II)morpholinedithiocarbamate complexes with P,P-ligands in the coordination sphere of composition [Ni(morphdtc)(P,P)]X and [Ni2(morphdtc)2X2(P,P)], resp. [(X = NCS-, ClO4 _, I-; P,P = 1,2-bis(diphenylphosphino)ethane (dppe), 1,4-bis(diphenylphosphino) butane (dppb), 1,6-bis(diphenylphosphino)hexane (dpph), 1,1_-bis(diphenylphosphino) ferrocene (dppf); morph = C4H8O; dtc = S2CN-)] have been isolated. These complexes have been characterized by elemental analysis, IR and UV-VIS spectroscopy, thermal analysis, magnetochemical and conductivity measurements. X-ray structural analysis of [Ni(morphdtc)(dppf)]ClO4_C2H5OH confirms the NiS2P2 chromophore with a slightly distorted square arrangement around central atom.
