“…The τ 4 parameter characterizing the geometry of the coordination polyhedron (coordination number 4) is equal to 0.91 [14]. The values of the Zn-N and Zn-Cl bond lengths and bond angles in complex I are comparable with similar values in the Zn(II) complexes with the aliphatic diamine derivatives [15][16][17][18][19][20]. In a molecule of complex I, the steroid fragment consists of fused alicycles (three six-membered (А, B, С) and one fivemembered).…”

Complexes [Zn(L)Cl 2 ] (I), Cu(L)Cl 2 • H 2 O (II), Zn(L 1 )Cl 2 • 0.5H 2 O (III), and Cu(L 1 )Cl 2 • 0.5H 2 O (IV) (where L and L 1 are the diaminopropylene and diaminoethylene derivatives of deoxycholic acid, respectively) are synthesized. The structure of mononuclear complex I is determined by X-ray structure analysis (CIF file CCDC no. 1875305). The coordination polyhedron of the Zn atom (Cl 2 N 2 ) is a distorted tetrahedron. According to the X-ray diffraction data, the crystals of compounds III and IV are isostructural. It is shown by IR spectroscopy that the structures of complexes II-IV are similar to that of complex I. In the solid phase, compounds L and L 1 possess photoluminescence in the visible spectral range (λ max = 440 and 415 nm, respectively). Complex formation with Zn 2+ ions does not change the photoluminescence properties of L and L 1 .

Then apurple solution was obtained. The crystals were obtained by evaporating the solution at room temperature for several days. Experimental detailsAll hydrogen atoms on carbon atoms were generated geometrically and refined as riding with d(C-H) =0.93 Å and Uiso(H) = 1.2 U eq(C). The imido group Hatom and water Hatoms were located from difference Fourier map and and were refined freely. DiscussionIn the past decade, much attention has been focused on the design and synthesis of macrocyclic polyamines, which can particippate in molecular recognition phenomena with different kinds of substrates, such as organic and inorganic cations, anions and neutral molecules [1,2]. Moreover, hexaaza macrocycles can form dinuclear metal complexes which in turn are capable of coordinating anions [3].The crystal structure of the title compound contains discrete molecules. The cobalt cation is five-coordinated by two chlorine atoms and three Na toms from ligand in at etragonal pyramidal coordination. Co1, N2, N3, Cl1 and Cl2 atoms are almost coplanar and the bond angle sum around cobalt is 358.5°.T he Co1-Cl1 and Co1-Cl2 distances are 2.489(1) Å and 2.351(1) Å,respectively. The mean Co-Ndistance is 2.053 Å.The chloroform and water molecule do not coordinate the cobalt center.

Source of materialAn chloroform solution of 3,7,11,18,22,26-hexaazatricyclo-[26.2.2.2 13,16 ]tetratriaconta-1(31), 13(34),14,16(33),28(32),29-hexaene (0.1 mmol) was added to as olution of nickel chloride (0.2 mmol) in methanol (5 ml). Then ag reen solution was obtained. The green crystals were obtained by evaporating the solution at room temperature for several days. Experimental detailsAll hydrogen on Catoms were generated geometrically and refined as riding atoms with d(C-H) =0.93 -0.97Å and U iso(H) = 1.2 or 1.5 U eq (C). The imido group Hatoms were located from difference Fourier map and were freely refined. The atoms C15 and O1 are disordered. The disordered atoms were included in the refinement anisotropically to give occupations of about 50 %. The hydrogen atoms associated with the water molecules were not found from the difference Fourier maps. DiscussionCurrently, the molecular recognition of macrocyclic polyamines is an area of intense chemical investigation with potential applications in areas such as the designing of positively charged or electron-deficient neutral abiotic organic receptor molecules [1][2][3].Moreover, hexaaza macrocycles can form dinuclear metal complexes which in turn are capable to coordinate anions [4]. The crystal structure of the title compound is formed by discrete molecules. The nickel cation is five-coordinated by two chlorine atoms and three Na toms from the Ll igand in at etragonalpyramidal coordination. Ni1, N2, N3, Cl1 and Cl2 atoms are almost coplanar and the bond angle sum about nickel is 356.6°. Ni1-Cl1 and Ni1-Cl2 distances are 2.347(1) Å and 2.439(1) Å, respectively. The mean Ni-Ndistance in the title compound is 2.066 Å.The methanol and water molecules do not coordinate the nickel center.
