Abstract

The asymmetric unit of the title compound, [Co(C₉H₁₂N₄O₃)₂](NO₃)₂·2H₂O, consists of a discrete cationic [Co(PLSC)₂]²⁺ complex unit [PLSC is 4-(2-carbamoylhydrazin-1-ylidene)-5-hydroxymethyl-2-methylpyridinium-3-olato], two NO₃ ⁻ and two water molecules. The two tridentate PLSC ligands of the cation are zwitterions related to each other by a non-crystallographic C ₂ axis. The Co^II ion is in a disorted octahedral coordination environment. The crystal structure is composed of alternating NO₃/H₂O and complex layers supported by extensive C—H (...)

Comment

Semicarbazones (SC) and thiosemicarbazones (TSC) are excellent chelating ligands of different denticity that possess a broad range of biological activity as antifungal, anti-viral, anti-malarian and anti-tumour agents (West et al., 1991). The synthetic, structural as well as the biological activity of TSC-based ligands have been explored to a greater extent than their SC-based analogues. In fact, only a handful of reports have been published revealing the syntheses and structures of complexes incorporating 3–hydroxy–5–hydroxymethyl–2–methyl– pyridine–4–carbaldehyde semicarbazone (PLSC) ligand (see for example Knezevic et al., 2003) and all the reports describe complexes incorporating one PLSC ligand except for a report by Leovac et al., (2007b), which includes the synthetic and structural descriptions of a complex with two PTSC ligands in its coordination sphere. It is worth noting that PLSC ligand can adopt three different forms in the coordination sphere of a transition metal namely neutral (but zwitterionic) H₂L, monoanionic HL^- (pyridinium deprotonation) and dianionic L^2- (both pyridinium and hydrazine deprotonation) forms (see Fig. 1).

Herein, we report the second PLSC-based complex ([Co(H₂L)₂].2NO₃.2H₂O, 1 (Figure 2), which contains two PLSC ligands in its coordination sphere. However, complex 1 includes both PLSC ligands in their neutral zwitterionic forms while in the corresponding complex reported by Leovac et al., (2007b) both ligands are in their monodeprotonated forms HL^-. Thus, the title complex 1 is the first bis-PLSC-based complex that contains neutral PLSC ligands.

The molecular structure for 1 is shown in Fig. 2 and it contains a discrete dicationic unit [Co(H₂L)₂]²⁺, two NO₃^- anions and two H₂O molecules. The crystal structure is connected by an extensive hydrogen-bonding network. The structure is best described as layered (Fig. 3) in which one layer consists of [Co(H₂L)₂]²⁺ units connected by alternating O16—H···O11 and C22—H···O2 hydrogen bonds additionally stabilized by a water molecule. The other layer consists of NO₃^- anions and water molecules that also form several hydrogen bonds with the first layer.

The values for certain bond lengths and angles of the ligand backbone (O(phenolic)–C–C–C–N (hydrazine)–N–C–O(carbonyl)) are crystallographic evidence used to determine which form (H₂L, HL^- or L₂^-) the PLSC ligand adopts once coordinated to a metal centre. For example, the first deprotonation of H₂L, forming monoanionic form HL^-, changes the carbonyl C—O from a double to a single bond and the hydrazine N—N from a single to a double bond. Further deprotonation to form L₂^- leads to a change in the C—N—C angle of the pyridine ring from 125° to 118°. Thus, the carbonyl C–O (1.249 (3) and 1.295 (3) Å) and N–N (1.368 (2) and 1.375 (2) Å) bond lengths, and the pyridine C–N–C angles (124.9 (2) Å and 124.19 (19) °) are the concrete evidence that the PTSC ligands are in their neutral (H₂L) forms in complex 1.

The environment around the central cobalt cation in 1 can be best described as a distorted octahedral geometry. In fact, the N6–Co–N21 angle (171.12 (7)°) is somewhat similar to the theoretical 180° , but the other two, symmetry-related, O2–Co1–O16 (154,44 (7)° ), and O18–Co1–O25 (162.82 (6)° ) angles greatly deviate from linearity due to the chelation rings strain. Furthermore, the angles formed by the phenolic and carbonyl O atoms and Co (O2–Co1–O18 and O16–Co1–O25) differ from 90° (83.21 (6) and 101.92 (7)°, respectively) confirming a distorted octahedral geometry around the central Co cation.

The ring-puckering parameters defined for the atom sequence O16(O25)–C15(C24)–C8(C23)– C7(C22)–N6(N21)–Co are Θ = 64.8 (7)°, Q1=0.142 (2) Å and Q2= 0.067 (2) Å corresponding to a twist (¹T₂) conformation while the six-membered ring has and a total puckering amplitude of 0.1572 (18) Å corresponding to a skew (1S2) conformation (Cremer & Pople , 1975). The O16(25) atoms are the only atoms in the chelate ligand which exhibit strong H bonding interactions with O11 of the NO₃^- anions. The geometry of NO₃^- groups do not deviate from the usual literature values and the summary of the H bonding (O–H···O, N—H···O and C—H···O) in 1 are given in Table 1.

Experimental

The title complex was prepared by the reaction of Co(NO₃)₂ .6H₂O and PLSC in a 1:1 molar ratio, using warm H₂O as the solvent. Brown single crystals of 1 were obtained after allowing the reaction mixture to stand overnight.
