NOVELTY - 5,6-Bis(porphinato)zinc(II)indane is new.    USE - The invention is for use as homogeneous or heterogeneous redox catalyst, or as electrocatalyst when interfaced to an appropriate electrode material. It may also be used in fuel cell, and for oxidative or reductive transformation. (All claimed)    ADVANTAGE - The invention is capable of binding diatomic, triatomic, or tetraatomic molecules; has homogeneous or heterogeneous redox catalyst activity; is capable of selectively oxidizing H, water, carbon monoxide, or nitric acid; is capable of selectively oxidizing a hydrocarbon; and/or capable of selectively reducing dinitrogen, dioxygen, carbon monoxide, nitric acid or carbon dioxide.    DETAILED DESCRIPTION - 5,6-Bis(porphinato)zinc(II)indane of formula (1), (2) or (3) is new.    porphinato group = substituted with 1-12C alkyl, 6-20C aryl, perhaloalkyl, 2-12C alkenyl or Cequivalent toC-R;    R = H, 1-12C alkyl or 1-20C aryl;    M, M' = metal ions;    RB1-RB8 = porphinato group or H.    The alkyl and aryl groups are optionally substituted with alkyl, aryl, alkoxy or aryloxy. At least one of RB1-RB8 or one of RA1-RA8 is perhaloalkyl, ethyne, alkynyl, oligynyl, or has the formula Cequivalent toCR. At least one of RA1-RA8 is electron withdrawing relative hydrogen (H) provided at least one of RB1-RB8 is not H. One of RB1-RB8 is electron withdrawing relative H. One of RA1-RA8 is electron withdrawing relative H provided all of RA1-RA8 are not perfluorophenyl. All of RA1-RA8 are electron withdrawing relative H provided at least one of RB1-RB8 is not H. At least one of RB1-RB8 or one of RA1-RA8 is haloalkyl. At least one of RB1-RB8 or one of RA1-RA8 is ethene, ethynyl, oligoenyl, or has the formula C(R-(C))=C(R-(D))(R-(E)).    R-(C), R-(D), R-(E) = H, 1-2C alkyl or 1-20C aryl.    INDEPENDENT CLAIMS are included for:    (a) an electrode where a compound of formula (I), (II) or (III) is absorbed;    (b) a fuel cell comprising a compound (I), (II) or (III); and    (c) a method comprising an oxidative or reductive transformation comprising contacting a reactant with a compound (I), (II) or (III).
