Two copper metallo-ligands [CuL1(H2O)] and [CuL2⊂(H2O)] [H2L1 = N,N′-ethylenebis(3-methoxysalicylaldimine) and H2L2 = N,N′-ethylenebis(3-ethoxysalicylaldimine)] have been utilized for the preparation of heterobimetallic eight CuIISnIV complexes [CuL1]2·[SnMe2Cl4]2–·(H2ED)2+ (1), [CuL1]2·[SnEt2Cl4]2–·(H2ED)2+·0.5H2O (2), [CuL1]2·[Sn(n-Bu)2Cl4]2–·(H2ED)2+ (3), [CuL1]2·[SnPh2Cl4]2–·(H2ED)2+ (4), [CuL1]2·[SnPh2Cl4]2–·(H2ED)2+·2MeOH (5), [CuL2]2·[SnMe2Cl2(H2O)2]·0.2H2O (6), [CuL2]·[Sn(n-Bu)2Cl2(H2O)] (7), [CuL2]2·[SnPh2Cl4]2–·(H2ED)2+ (8), and two CuIISnII systems [CuL1SnCl]+·[SnCl3]− (9) and [CuL2SnCl]+·[SnCl3]− (10) (ED = 1,2-ethylenediamine). Single crystal X-ray structure analyses indicate that 1–5 and 8 are three-component [1×2+1×1+1×1] salt cocrystals of two neutral mononuclear [CuL1]/[CuL2] moieties, one organometallic dianion [SnR2Cl4]2– (R = Me, Et, n-Bu, and Ph), and one doubly protonated 1,2-ethylenediammonium dication H2ED2+, while compounds 6 and 7 are two-component [1×2+1×1]/[1×1+1×1] cocrystals of one/two neutral mononuclear [CuL2] and one neutral organotin(IV) moieties. Compounds 9 and 10 are two-component salts which are comprised of heterometallic, diphenoxido-bridged, dinuclear CuIISnII cation [CuLSnCl]+ and SnII anionic residue [SnCl3]−. Interestingly, the formation of the salt cocrystals or cocrystals 1–8 and salts 9 and 10 can be well rationalized in terms of several noncovalent weak interactions (O–H···O/N–H···O/N–H···Cl/Cu···Cl/Sn···Cl/Sn···Cu/π···π) which result in the generation of a tetrameric associate in 7, one-dimensional topology in 3–5 and 8–10 and two-dimensional supramolecular associate in 1 and 2. The first metallo-ligand [CuL1(H2O)] produces similar three-component CuII···SnIV···diprotonated diamine salt cocrystals (1–5), attesting to the selectivity toward the formation of this type of compound, while the latter one [CuL2⊂(H2O)] displays a diverse structure forming capability by producing a CuII···SnIV···diprotonated diamine salt cocrystal (8) and two CuII···SnIV cocrystals (6 and 7). Interestingly, no such selectivity is observed for their heterometallic CuIISnII derivatives (9 and 10) which are similar two-component salts and completely different from 1–8. The current study illustrates an excellent example of structural diversity in heterometallic CuIISnII/IV complexes depending on the ligand substitution and metal oxidation state. Moreover, a heterometallic system, such as 1–5 and 8, containing ammonium-stannate adduct (X–NH3·SnX6, X = any) is not known according to the search made on the Cambridge Structural Database (CSD).

The present study deals with one dimer‐of‐dinuclear type compound, [{CuIILAgI(NO3)}2] (1), one pentametallic and metal‐centered rectangle type compound, [BaII(CuIIL)4](ClO4)2 (2), and one dinuclear based two‐dimensional coordination polymer, [CuIILCdII(μ1,5‐dicyanamide)2]n (3), where H2L=N,N′‐bis(salicylidene)‐1,4‐butanediamine. The syntheses and crystal structures of 1–3, electrospray ionization mass spectra in positive mode of 1 and 2 and variable‐temperature magnetic properties of 2, are described. Two symmetry related diphenoxo‐bridged dinuclear CuIIAgI moieties are interlinked in 1 by Ag–π (η2‐) bonds to form dimer‐of‐dinuclear type structure. One diphenoxo‐bridged dinuclear CuIICdII moiety is interlinked with four symmetry related dinuclear moieties by four μ1,5‐dicyanamide ligands, which link CdII centers, to generate two‐dimensional polymeric structure in 3. In the [BaII(CuIIL)4]2+ cation in 2, the BaII ion is coordinated to two μ‐phenoxo oxygen atoms of each of the four [CuIIL] fragments; the four copper(II) ions are positioned to form an approximate rectangle, i. e., the pentametallic [BaII(CuIIL)4]2+ cation in 2 is a metal‐centered rectangle. ESI‐MS positive of 1 and 2 have been recorded and the ions in the spectra have been reasonably assigned. Variable‐temperature magnetic studies of 2 reveal very weak antiferromagnetic interaction (J=–0.14 cm–1) between the copper(II) ions. The structure of 2 represents a new type among compounds from related ligands.

“…In contrast, the cocrystals containing metal coordination compounds are infrequently reported, and this situation is due to the fact that, commonly, the metal complexes have different coordination modes, and the compounds with different coordination modes rarely possess similar lattice packing forces and exhibit similar crystallization kinetics. 33−38…”

Cocrystallization may alter material physicochemical properties; thus, the strategy of forming a cocrystal is generally used to improve the material performance for practical applications. In this study, two transition-metal complex cocrystals [Zn(bpy) 3 ]H 0.5 BDC·H 1.5 BDC·0.5bpy·3H 2 O ( 1 ) and [Cu 2 (BDC)(bpy) 4 ]BDC·bpy·2H 2 O ( 2 ) have been achieved using a hydrothermal reaction, where bpy and H 2 BDC represent 2,2′-bipyridine and benzene-1,3-dicarboxylic acid, respectively. Cocrystals were characterized by microanalysis, infrared spectroscopy, and UV–visible spectroscopy. Cocrystal 1 contains five components and crystallizes in a monoclinic space group P 2 1 / n . The H 0.5 BDC 1.5– , H 1.5 BDC 0.5– , and H 2 O molecules construct three-dimensional H-bonding organic framework; the [Zn(bpy) 3 ] 2+ coordination cations and uncoordinated bpy molecules reside in channels, where two coordinated bpy ligands in [Zn(bpy) 3 ] 2+ and one uncoordinated bpy adopt sandwich-type alignment via π···π stacking interactions. Cocrystal 2 with four components crystallizes in a triclinic space group P -1 to form alternating layers; the binuclear [Cu 2 (bpy) 4 (BDC)] 2+ cations and uncoordinated bpy molecules build the cationic layers, and the BDC 2– species with disordered lattice water molecules form the anionic layers. Cocrystal 1 shows intense photoluminescence at an ambient condition with a quantum yield of 14.96% and decay time of 0.48 ns, attributed to the π* → π electron transition within phenyl/pyridyl rings, and 2 exhibits magnetic behavior of an almost isolated spin system with rather weak antiferromagnetic coupling in the [Cu 2 (bpy) 4 (BDC)] 2+ cation.
