Abstract
- In the title compound (systematic name: bis{1,2-bis[12,14-dioxa-13-phosphapentacyclo[13.8.0.02,11.03,8.018,23]tricosa-1(15),2(11),3(8),4,6,9,16,18(23),19,21-decaen-13-yl]ethane}dichloridoiron(II) dichloromethane disolvate), [FeCl2(C42H28O4P2)2]·2CH2Cl2, the FeII ion lies on a crystallographic twofold rotation axis and is coordinated by four P atoms from two (R,R)-1,2-bis(binaphthylphosphonito)ethane (BPE) ligands and two Cl ligands in a distorted cis-FeCl2P4 octahedral coordination geometry. In the crystal, weak C—H...O and C—H...π interactions link the molecules into layers lying parallel to (001). A weak intramolecular C—H...O hydrogen bond is also observed. The asymmetric unit contains one CH2Cl2 solvent molecule, which is disordered over two sets of site with refined occupancies in the ratio 0.700 (6):0.300 (6).
