Hydrothermal synthesis and crystal structure of two hetero-transition metal polymers: [Co(1,10-phen)2(V2O4) (O3PCH2CH2CH2PO3)]n and [{Co(1,10-phen)2}2(V4O10) (O3PCH2CH2CH2CH2PO3)(2H2O)]n
Abstract
A helical chain of [Co(1,10-phen)2(V2O4)(O3PCH2CH2CH2PO3)]n
(1) and a stepped chain of [{Co(1,10-phen)2}2(V4O10)(O3PCH2CH2CH2CH2PO3)(2H2O)]n
(2) have been synthesized under hydrothermal conditions using [Co(1,10-phen)2]2+ as the metal-organic subunit and organic diphosphonate
