Abstract

Single crystals of the title heterometallic compound, [Fe(C(12)H(8)N(2))(3)][Cr(NCS)(4)(C(12)H(8)N(2))](2)·3CH(3)CN·H(2)O or [Fe(Cphen)(3)][Cr(NCS)(4)(phen)](2)·3CH(3)CN·H(2)O, were pre-pared using the one-pot open-air reaction of iron powder, Reineckes salt and 1,10-phenanthroline (phen) in acetonitrile. The asymetric unit consists of an [Fe(phen)(3)](2+) cation, two [Cr(phen)(NCS)(4)](-) anions, three acetonitrile solvent mol-ecules and a water mol-ecule. The Fe and Cr atoms both show a slightly distorted octa-hedral FeN(6) and CrN(6) coordination geometry with adjacent angles in the range 79.67 (12)-95.21 (12)°. No classical hydrogen bonding involving the water molecule is observed.
