摘要：

(davaH(2))[FeCl4](2) crystallizes at room temperature from aqueous solutions of 2,4-diamino-vinamidinium hydrochloride, (davaH)Cl, and FeCl3 in 3M HCl in the orthorhombic space group Pca2(1) with a=14.108(3), b=16.502(3), c=18.919(4) Angstrom, Z=8. The structure consists of diprotonated tricyclic (davaH(2))(2+) cations and slightly distorted tetrahedral [FeCl4](-) anions. The cations are bent around the central heptacycle forming boat-like units. One of the two independent cations is disordered between two positions. Some interatomic distances N ... Cl are interpreted in terms of N-H ... Cl hydrogen bonds.
