cis-Bis[(1-adamantylmethyl)amine-[kappa]N]dichloridoplatinum(II) N,N-dimethylformamide solvate

F. D. Rochon and C. Tessier

Abstract top

The asymmetric unit of the title compound {systematic name: cis-dichloridobis[(3,7-dimethylbicyclo[3.3.1]non-1-ylmethyl)amine-[kappa]N]platinum(II) N,N-dimethylformamide solvate}, [PtCl2(C11H19N)2]·C3H7NO, consists of two metrically similar Pt complexes and two dimethylformamide solvent molecules. Each PtII center is coordinated by the amine groups of two (1-adamantylmethyl)amine ligands and two Cl atoms in a cis-square-planar arrangement. The PtII centers lie slightly outside [0.031 (4) and 0.038 (4) Å] the coordination planes. The N-Pt-N and Cl-Pt-Cl angles [92.1 (4)-92.30 (11)°] are slightly more open than the N-Pt-Cl angles [87.3 (3)-88.3 (3)°]. N-H...O and N-H...Cl intermolecular hydrogen bonds are observed, forming two discrete pairs of complexes and solvent molecules.

Comment top

Cisplatin [cis-Pt(NH3)2Cl2] is now a well known antitumor drug, but it has numerous side effects and resistance to the drug is an important problem. Replacement of the NH3 ligand by an amine more compatible to the human system might possibly surmount some of these problems. One such amine is the polycyclic cage molecule adamantanamine, which has been demonstrated to exhibit both antiviral (Hay et al., 1985; Widell et al., 1986) and antitumor activity (Ho et al., 1972). The synthesis and the spectroscopic study of PtII compounds with adamantanamine derivatives have been reported (Rochon et al., 1993).

In the title compound (one of the Pt complex is shown in Fig. 1), the Pt metal center exhibits a cis square-planar geometry formed by two amine groups from (1-adamantylmethyl)amine and two Cl atoms. The Pt centers are slightly outside [0.031 (4) and 0.038 (4) Å] the N2Cl2 planes. The bulky adamantane cycles slightly open the N—Pt—N angles [92.1 (4)°] compared to the N—Pt—Cl angles [87.3 (3)–88.3 (3)°]. However, the Cl—Pt—Cl angles are also opened to the same extent [92.17 (11)–92.30 (11)°]. The Pt—N [2.026 (9)–2.056 (9) Å] and Pt—Cl [2.304 (3)–2.312 (3) Å] are normal as well as all other bond distances and angles.

The asymmetric unit of the title compound is described as two crystallographically independent Pt complexes and two dimethylformamide (DMF) solvent molecules linked by N—H···O hydrogen bonds (Fig. 2) between the amine groups and the O atoms from the DMF molecules. N—H···Cl hydrogen bonds between the amine groups and Cl atoms from symmetry equivalent complexes are also observed, forming discrete pairs of complexes and solvent molecules (Fig. 3).

For the antiviral and antitumor activity of Pt complexes with polycyclic cages such as adamantamine, see: Hay et al. (1985); Ho et al. (1972); Widell et al. (1986). The synthesis and spectroscopic characterization of the title compound is described by Rochon et al. (1993).

Experimental top

One mmol of K2[PtCl4] and 2 mmol of (1-adamantylmethyl)amine were heated in a DMF solution at 80°C for 3 h. The solution was concentrated, cooled to 0°C and the KCl was filtered off. The mixture was evaporated to dryness and the residue washed with ether, acetone and then with water. After drying, the residue was washed with ether and dried. Yield 68%, dec. 195–225°C, ν(Pt—Cl) IR 341, 325, Raman 334, 325 cm-1, 195Pt NMR -2213 p.p.m. The crystals were recrystalized in DMF for crystallographic studies.

Refinement top

H atoms were placed at calculated positions (C—H = 0.95–1.00 Å, N—H = 0.92 Å) and were allowed to ride on their parent atoms, with Uiso(H) = 1.2Ueq(C,N) for the CH, CH2 and NH2 groups and Uiso(H) = 1.5Ueq(C) for the CH3 groups. The highest residual electron density was found 1.0 Å from Pt2.
