“…With the relaxation of this combination, other possibilities emerge, rendering the classification of the large remainder more variable Ϫ on passing from [Li(dmp) 2 ] ϩ to [Na(dmp) 2 ] ϩ , the coordination sphere of the metal atom may expand to become five-coordinate as in the preceding paper [1]; no other [M(dmp) 2 ] ϩ arrays have been isolated at this stage, all other MX : dmp (1:2) combinations being as previously described of the form [XNa, K(dmp) 2 ](·S). With 2 ] ϩ array has two comparable large angles, in a cation of putative 222 symmetry, and, in a number, these angles become so large that the array is incipiently planar, approaching mmm symmetry. Here, in both types, we find the cations variously disposed, in rather high symmetry space groups, relative to associated symmetry elements, namely crystallographic 2-axes.…”

In the preceding paper an array of salts of MX : L(:S) (1:2(:n)) stoichiometry of simple mononuclear form, with coordinated X or S were described, MX ϭ simple group 1 salt, L ϭ 1,10-phenanthroline ('phen') or 2,9-dimethyl,1,10-phenanthroline ('dmp'), crystallized from (methanol) solution and characterized by single crystal X-ray studies. This paper describes a parallel isostoichiometric array in which the metal atoms exist in environments of nitrogen atoms only, of polymeric/ionic form. Adducts LiX : dmp : MeOH (1:2(:n)), isomorphous [Li(dmp) 2 ]X(·MeOH), are described for X ϭ I, ClO 4 (nϭ1), O 3 SCF 3 (ϭ 'triflate', tfs) (n ϭ 0). Adducts MX : phen (:MeOH) (1:2(:n)) form a wide-ranging array of structures with discrete anions and stacked cations with a variety of metal geometries and L coordination modes, the stacks discrete

The coordination chemistry of 1,10‐phenanthroline (phen) and sodium 1,3‐benzothiazole‐2‐thiolate (SBT) with selected s‐block elements has been investigated. Four metal complexes were prepared and their structures were characterized using a variety of analytical techniques including infrared, UV–visible, 1H NMR and 13C NMR spectroscopies, elemental analysis, mass spectrometry and single‐crystal X‐ray diffraction. The reactions of phen and SBT with M(X)n (M = K(I), Cs(I), Mg(II), Sr(II); X = OH−, CO3−, Cl−; n = 1, 2) in MeOH–H2O yielded one‐dimensional chains of both potassium [K2(phen)2(BT)2(H2O)4]n (1) and caesium [Cs(phen)(BS)(H2O)]n (2) (where BT = 1,3‐benzthiazole‐2‐thiolate and BS = 1,3‐benzthiazole‐2‐sulfinothiolate) and mononuclear complexes of both magnesium {[Mg(phen)(H2O)4](BT)2·phen} (3) and strontium {[Sr(phen)2(H2O)4](BT)2} (4). In these complexes, phen binds via an N,N′ chelate pocket, while the monoanonic BT− ligands either coordinate in a bidentate fashion (in the case of 1) or remain uncoordinated (in the case of 3 and 4). In complex 2, SBT ligand was oxidized in situ into a new BS ligand. The sulfinothiolate oxygen atoms in BS coordinate with caesium in a tridentate fashion. Complexes 1–4 were evaluated against urease for enzyme inhibition. The complexes displayed significant inhibition with IC50 values in the range 10.8–45.8 μM. In order to examine the structure–activity relationship, the complexes were docked at the active site of urease. Docking results clearly demonstrate the binding of each complex within the active site of the enzyme.

Crystallizations of simple group 1 metal salts MX with N,NЈ-bidentate aromatic ligands 1,10-phenanthroline ('phen') and the hindered 2,9-dimethyl,1,10-phenanthroline ('dmp'), as well as complexes of other forms and stoichiometries described in accompanying papers, have yielded a broad array of simple mononuclear adducts of 1:2(:n) MX : L (:S) stoichiometry from methanol solutions. One of these, NaBr : phen : MeOH (1:2:2) contains a sixcoordinate metal atom, being ionic [(MeOH) 2 Na(phen) 2 ]Br, but the majority contain five-coordinate metal atoms, being either ionic (one example only, [(MeOH)Li(phen) 2 ]Cl·MeOH) or neutral 1829 [XML 2 ] species, the latter for the combinations MX : phen (M ϭ Li, X ϭ I, ClO 4 , tfs (ϵ 'triflate', F 3 CSO 3 ) (a new form), NO 3 ; M ϭ Na, X ϭ Br, I, ClO 4 , NO 3 ) and MX : dmp (M ϭ Na, X ϭ NCS, Br, I, PF 6 , ClO 4 ; M ϭ K, X ϭ I), the (coordinating) polyatomic anions being unidentate, and the coordination geometries distorted trigonal bipyramidal.
