OBJECTIVE The housing preferences of persons with severe mental illness living in three types of community residences were examined, as were their perceptions of problems in these settings and the relationships between clients' and family members' housing preferences and perceptions of problems. METHODS A closed-ended questionnaire was developed to gather(More)
In the structure of the title compound, [Fe(C(5)H(5))(C(6)H(12)N(4))(CO)(2)]BF(4), the arrangement around the Fe(II) atom corresponds to that of a three-legged piano stool. The cyclo-penta-dienyl ligand occupies three coordination sites of the apical position in a η(5) fashion, while two CO ligands and one N atom of the hexa-methyl-ene-tetra-mine ligand(More)
The title compound, C(38)H(30)OP(2)S·CH(2)Cl(2), belongs to the xanthene family of ligands containing S- and O-donor atoms in the central heterocylic ring. Positions 2 and 8 on the xanthene backbone are functionalized with methyl groups to allow for the selective functionalization of the backbone at positions 4 and 6 with diphenyl-phosphanyl units. The(More)
In the title compound, [Fe(C(10)H(15))(C(6)H(12)N(4))(CO)(2)]BF(4), the arrangement around the Fe(II) atom corresponds to a three-legged piano stool. The penta-methyl-cyclo-penta-dienyl (Cp*) ligand occupies three coordination sites, while two CO ligands and one N atom of the hexa-methyl-ene-tetra-mine ligand occupy the remaining coordination sites,(More)
The title compound, [Fe(η(5)-C(5)H(5))(NH(2)CH(2)CHBrCH(2)Br)(CO)(2)](BF(4)) contains an Fe(II) cation with a three-legged piano-stool coordination. The NH(2)CH(2)CHBrCH(2)Br ligand contains a chiral carbon atom. The Fe-N bond length is 2.011 (3) Å and the Fe-Cp centroid distance is 1.7189 (5) Å. In the crystal, the ions are linked via two N-H⋯F(More)
The asymmetric unit of the title compound, [Fe(2)(C(5)H(5))(2)(C(2)H(8)N(2))(CO)(4)](BF(4))(2), contains two half-cations, each located on a center of symmetry, and two tetra-fluorido-borate anions. The iron atoms adopt a three-legged piano-stool geometry. All amine H atoms are involved in N-H⋯F hydrogen bonds, which consolidate the crystal packing along(More)
In the crystal of the title compound, C(15)H(23)NO(5)S, mol-ecules are linked through N-H⋯O and O-H⋯O hydrogen-bond inter-actions, resulting in centrosymmetric dimers in which the N-H⋯O inter-actions generate R(2) (2)(12) rings and the O-H⋯O inter-actions generate R(2) (2)(14) rings. Weak inter-molecular C-H⋯O inter-actions are also observed.
In the structure of the title compound, [Fe{η(5)-C(5)(CH(3))(5)}(NCCH(3))(CO)(2)]BF(4), the arrangement of ligands around the Fe atom is in a pseudo-octa-hedral three-legged piano-stool fashion in which the penta-methyl-cyclo-penta-dienyl (Cp*) ligand occupies three apical coordination sites, while the two carbonyl and one acetonitrile ligands form the(More)
In the structure of the title compound [Fe(2)(C(5)H(5))(2)(CHO(2))(CO)(4)]BF(4), each Fe(II) atom is coordinated in a pseudo-octa-hedral three-legged piano-stool fashion. The cyclo-penta-dienyl ligand occupies three fac coordination sites while the two carbonyl ligands and formate O atom occupy the remaining three sites.
There are two symmetry-independent mol-ecules in the asymmetric unit of the title compound, C(13)H(19)NO(3)S. The cyclo-hexane rings in the two mol-ecules adopt chair configurations. The hydr-oxy and amino groups on the cyclo-hexane ring assume axial and equatorial orientations, respectively, with respect to the plane of the ring. The crystal structure is(More)
